This is a pretty simple version of minesweeper I made a while ago, mostly to to try out a few visual tricks. In particular I'm happy with how the half-offset tiles look. I doubt I'll work on it more, but I wanted to upload it in case someone found it interesting.

Mountain Racing 1.4

by klunkoplunko

[Click to Play]

	[72x8]

Welcome to the mountain course! Race through tricky canyons and perilous bridges, and aim for a good time!

My personal best is 54.2 seconds. That is unless you count a particularly nasty shortcut mid-way through the track, with which I got 38.5 seconds.

Good luck!

Simple IK

by klunkoplunko

[Click to Play]

This is a simplified kind of inverse kinematics. The function finds an arm position that will reach a certain point. Simplified in the sense that this is done just using vector maths instead of an actual IK algorithm. You can look at this desmos graph if you want to see the maths more closely.

Input:

Shoulder position (sx,sy)
Hand position (ex,ey)
Arm length (dist)

Output:

Elbow position (kx,ky)
Hand position (ex,ey)

The arm can only reach so far, hence the returned hand position. You can see the difference if you try to over-extend the arm.

It hasn't been optimised for tokens and the variable names don't really make sense, so apologies about that

function inv_kin(_sx,_sy,_ex,_ey,_dist)
	local mx,my=(_ex-_sx)/2,(_ey-_sy)/2
	local mm=sqrt(mx^2+my^2)
	if mm>_dist then
		return {kx=_sx+_dist*mx/mm,ky=_sy+_dist*my/mm,ex=_sx+2*_dist*mx/mm,ey=_sy+2*_dist*my/mm}
	end
	local km=sqrt(_dist^2-mm^2)
	local kx,ky=km*-my/mm,km*mx/mm
	return {kx=_sx+mx+kx,ky=_sy+my+ky,ex=_ex,ey=_ey}
end

And in the draw function

local ik=inv_kin(body_x,body_y,hand_x,hand_y,40)
...
spr(3,body_x-4,body_y-4)
spr(2,ik.ex-4,ik.ey-4)
spr(1,ik.kx-4,ik.ky	-4)

If you want to change the elbow direction, change the line
local kx,ky=km*-my/mm,km*mx/mm to
local kx,ky=km*my/mm,km*-mx/mm (swap the sign of mx and my)

Picocross

by klunkoplunko

[Click to Play]

This is a work-in-progress game of picross. Has someone else used the name picocross? Probably, but this is my one!
It currently only has one puzzle and the game ends once you beat it.

How to play

Use arrows to move the cursor.
Press (X) to place a tile and (O) to place a cross. You can use the crosses to show where tiles definitely are not.
Press (X) or (O) to remove a tile / cross.
Press (X) to highlight / un-highlight a number. You can do this to keep track of which numbers have been solved.

How to play picross

To discover the hidden picture, you need to determine where the tiles must be placed.
For each column and each row you are given a set of numbers. These numbers tell you how many consecutive tiles are in that row or column. Multiple numbers means multiple 'blocks' of consecutive tiles in the same order as the numbers, that are separate from each other.

To do

'Easy' mode (gives a penalty when a tile is wrong, hints, etc.)
More puzzles w/ menu
Larger puzzles (I have plans to go up to 64x64, or even 128x128, ft. compression)
Graphical polish

Trampoline!!

by klunkoplunko

[Click to Play]

	[8x8]

This is a score-based game where you must collect orbs while bouncing on a trampoline. The more orbs you get in a single jump, the higher combo you'll get. Can you get a combo of 4 or more?

If you're having trouble gaining height, remember that the middle of the trampoline is the bounciest, and to use your jump at the peak of the bounce to gain momentum.

Controls

Left and Right to move
Up to jump
Down to slam downwards

Topdown jumpy sort of thing

Topdown jumpy sort of thing

by klunkoplunko

[Click to Play]

	[64x8]

This is a topdown, psuedo-3D platformer I've been working on. There's no actual game to it yet other than getting a few coins. It's definitely a little janky and not optimized at all but I'm still quite proud of it.
I don't know if I'll ever get around to making the game part of the game so I thought I'd submit it in case anyone was interested.

Controls

Arrow keys to walk
(X) to jump

	[48x8]

Important! I actually made this version ages ago, but I published it as a separate cartridge for some reason. Anyways, here's the new version.

An arcade-y game based on the Mario Bros. Game and Watch.
This is the second version of my first PICO 8 game. Hope you enjoy it!

How to Play

Move both workers to carry the products up the conveyor belts. Don't let them fall!
Alternatively, control one worker and have a friend control the other in a sort of co-op!

In later levels you will also need to keep track of the winch and siren.
The winch will slowly drop. Too far, and it will break. Move the guy on the right up to the wheel on the top to raise it back up.
Steam will build up over time, as indicated by the siren. Once the siren turns red, the guy on the left must hit the button on the bottom to release it all. Too late, and it will explode!

New things!

You can now save and view highscores! In addition:

Different products

	[8x8]

Eventually you will encounter faster moving electronics. Try and keep up!

	[8x8]

In later levels you will also need to deal with valuables. They move slow, but the game will be over if even just one falls.

Bonuses

	[24x8]

The first bonus will appear between other products. It will fall quickly, but won't take a life. Collect it for points.
The second appears if you made a delivery without dropping anything. Collect it for extra points.
The third acts much like the first, but will return if delivered. Keep it going for a bunch of points!

Powerups

	[32x8]

Deliver a powerup to gain its effects.
The wrench will give a life to both workers.
The pipe will open the pipe on the right, allowing you to see ahead.
The weight will raise the winch for you.
The flame will pause the fire valve for a moment.

Controls

This guy:

	[8x8]

Move up and down using [X] and [O]

The other guy:

	[8x8]

Move up and down using [Up] and [Down]

You don't need to press a button for them to do something, they'll do it if they're in the right spot.

These controls make more sense on keyboard than on controller. You can swap them in the main menu if needed.
You may also pause with [Left] or [Right].

Other things

The controls are now saved between sessions.
There also may or may not be a title screen secret.

I didn't get around to testing the powerups very much so they may be buggy. I also didn't get around to tweaking the difficulty, so feedback is appreciated. I can't guarantee I'll get around to it though
