I really enjoyed the game, I think the mechanics are very cool.
I had a few problems:
1. the green indicator is very hard to see sometimes I just guessed where it is
2. on level 4 - one way I noticed there are a few tiles I can't walk onto idk why I am pretty sure the target is the top left corner(not sure) and there were a few problems for me in this level
other than these problems this game is interesting
