The Good:
- Cool concept - haven't seen a game like this before
- The mechanics were well implemented - you created some interesting puzzles with the mechanics you introduced
- Nice and simple tutorial - teaches the player everything they need to know
Could improve:
- Music keeps restarting every level - this can get pretty annoying, but thankfully your music wasn't loud. I can see you're using Unity. Look into the "DontDestroyOnLoad()" function
- Poor scaling - the game didn't scale properly, but it's not a big deal since it was playable
- Short and easy - should've added more levels and made them more challenging
Overall:
A fairly solid game. Felt a bit short, but sometimes you just run out of time. The levels that you did create were pretty fun to play through though.
