UPDATE v1.4!!! 2P mode is now in beta!!
I made my first game today and yesterday, rolly the dot’s adventure! This is only beta, so
I will be updating a lot, so you might have to check this a lot.
I built it in half-block, half-code.

Copy and paste into circuitblocks and compile.
It might not be that good though 
How to play
Either get the game for the nibble and select the menu option “How to play”, or look through the code.(Hint: line 377)
