Hey, fellow "bot using blocks to get to the goal" game developer!
I finally tried out your game, and I enjoyed it very much! I'll finish it another day, but despite not getting to the end I loved everything you worked on!
Since the game is already great, I can only nit-pick and suggest you to make the pixel art consistent (background-foreground), and to make collisions more consistent/obvious. Without an obviously small gap, it feels weird to see perfectly-shaped blocks can't go through perfectly-shaped holes.
Anyway, that didn't ruin the fun for me. It's a wonderful game, congrats! :)
