Pretty nice game and easy to pick up!
For me the theme isn't really there, for example I could say the green cube is a magic cube not an AI and the game would still work. It fits the theme but not that much, but still the concept is cool and nicely executed !
The graphics looks good but I feel like your palette could be a bit better, maybe it's just me but the flashy blue walls almost do not feel like walls.
Good luck and have fun on your game dev journey !
