I must confess… this is exactly my sweet spot in puzzle games - a little rgb training included! very very well done! and great audio too - fits perfect
one improvement suggestion: if you hold down an arrow key, it should repeat - not so fast like in a text editor, but auto-move with like 2 steps per second or so would be nice - slow enough to stop where you want but fast enough to get the feeling of moving forward.
Oh, and leave a note that the cursor keys must be used – tried wasd, mouse… needed a bit to figure out it’s cursor keys only.
