WOW!! that level 2 was tough! the idea is really interesting, sometimes I felt like I was calculating a chess move ("if I do this they'll do this, and then I'll do this and they'll do this"), It felt really good when I pulled it off lol. By some miracle I got level 9 on my first try, that was probably the only level I completed without deaths! The music was nice and relaxing and the digging sound effect felt oddly satisfying.
Some of the puzzles felt very rewarding when you realized what you had to do, one specifically, which looked like you were being chased by two ants, but actually relied on you stepping towards one of the ants, which would move away on the first turn, had a very clever design. Other levels felt a bit harder and more constrained in their solutions, relying more in trial and error than thinking. But overall it was really interesting and the presentation was great through and through!
