So I'm working on another game

The previous ones I worked on were a little... I guess... too much for my current PICO-8 skill. This new one will not be as big as the others.
Guess I'm both worried about my skill and the amount of coding I'd need for it.

So I was working on the map in PICO-8 when I found some tiles I never placed, so I started erasing them. Later I saw a chunk of my spritesheet was erased, so I fixed that manually. Later the same thing happened and found that the tiles are related to the colors in the sprites. Why is this?

🤔 what could I be presenting?
what could possibly concern me so much I require the changing of keys?
who is Aris? (wait, I'm the one making this post...)

Random bird and random person said bird will be attacking.

	[16x16]

	[8x8]

In ROBLOX I am also learning how to code, but one thing stands out that I feel should be necessary.

What is supposed to happen is that it runs:

function _init()
   cls()
   spr(192,20,20,4,4)
   wait(3)
end

But it errors with
"Runtime error line 4 tab 0
wait(3)
Attempt to call global 'wait' (a nil value)
In _init line 4 (tab 0)
At line 1 (tab 1)"

Is there a way to make the program wait a few seconds without taking too much space?

Thanks :)

As mentioned by the title, I have two questions.

Question 1: What is the Devkit and how is it enabled? (Just curious.)

Question 2:
If you see this character in an RPG:

	[16x16]

would you prefer no eyes or yes eyes?
For reference here is a bird I made for the same RPG. (please tell if it's a good bird, never really did pixel bird before)

	[8x8]

Also for this one, no eyes or yes eyes?

1 no

Thanks for reading :)
