"Gravity Wrangler"
Each world hurtles into the deep, feigning a wandering heart, accelerating their demise. What would they think if they realized that, through the eons, I was the only one standing between them and the frozen abyss...

NOTES
I was very lucky to be picked for the livestream of the game jam's submissions, and I had a great time working on what I would describe as 'Blood Peggle' - I hope you enjoy it as much as I liked making it. I do think we made it a bit too hard, but given that you can start on any level you like, I've opted to leave it as is.
CREDITS
This was a project for the A2B2 Game Jam, made by Remagamer and Eleven. You can follow me at https://twitter.com/Remagamer1 if you are so inclined.

This is something I made for a request on reddit a while ago, and thought I'd share it here.
The timing objects are excellent for using in any game that needs precise timing actions. The timer bars are something I added later, and are not perfect.
> Hope this helps somebody! Timing can be a real headache. But this is very user friendly. There's a full section of notes in the cartridge!
This is a simple way to browse the internal pico-8 api, which I posted about on Twitter a while back.

I'm creating a small game where a player is on a grid of tiles. I want the player to move smoothly from one tile to the next, not appear instantly in the next tile. I tried to create a delay loop in the update function when the direction key was pressed, but the sprite still appears instantly 8 pixels to the left, right, etc.
The sprite is drawn, then when I hit, say, right, then the loop increments the x position, but it doesn't draw the sprite again until the loop is completed. How would I go about moving the sprite 1 pixel per frame for 8 pixels then stop?
I can sort of imagine what I need to do, but it's just a sort of jumble in my mind right now!

Add speech synthesis to your games with Speako8, a speech synthesis library for PICO-8 in under a thousand tokens! It's loosely based on a Klatt synthesizer and will remind some folks of Software Automatic Mouth (S.A.M.)
To add Speako8 to your games, copy and paste the library below:

Let me clear things up:
I don't know trigonometry.
I made this from my incredibly basic understanding of it.
Do not expect this to be great.
But I mean, it kinda gets the job done?
anyway, here it is.
PHOTOSENSITIVITY WARNING: If the character reaches the mouse, it moves left and right fast.
(Please explain to me how to do trig for this in the comments)

PICO-Patch is an 2OP instrument and music sequence creator for PICO-8, developed by MegaSparky as a spiritual successor to his independently released tool 4OP-8. It allows users to create instruments by mixing two sine wave operators in different ways and create melodies with them.
Controls:
All actions are controlled with the mouse cursor/touchscreen, except for playing notes. To trigger a note outside of play mode, press (o) - z on the keyboard - and use the d-pad/arrow keys to change the note that you play; left and right changes it to the previous and following one respectively, while up and down switch octaves.
Creating instruments:
PICO-Patch features four types of sound synthesis: phase modulation (PM), amplitude modulation (AM), ring modulation and additive. The "ADSR" parameters allow you to modify each operator's attack, decay, sustain and release respectively. The "V" meter controls the operator's global volume, and the "M" parameter defines the multiplication of its frequency.
i'm not managing to get the music player to play music, and all the controls also seem to be doing nothing. see this post for an example:
https://www.lexaloffle.com/bbs/?tid=43733
i also checked with more recent posts that use the music player. i tried both latest firefox and chromium on linux mint 20.3. i don't have the tab muted, and other applications as well as other sites and the cart player still play sound

Eye Of Yox
About
A short wave-based shmup made following the Lazy Devs Basic Shmup Showcase.
Survive the waves of aliens and defeat the mighty Eye of Yox !
How to play
- Arrow keys to move
- Tap X to shoot
- Hold and release X for a powerful charged shot
- Collect pickups from enemies (score, extra life, defensive shield)
- Survive the waves of aliens until the final boss
Features
- 9 waves + 1 boss
- 4 different alien types + "elite" variants
Made this as a birthday gift for my wife.
I hope she enjoys playing it on her new retro device.
Instructions:
The goal is to save all the bunnies from the wolf/fox
- collecting all coins will automatically purchase & place the burrow
- collect all the keys to unlock the burrow
- direct the bunnies safely into their new home.
