Very nice game! I really liked the art style of the game and how it progressively got more difficult. The music created this eerie atmosphere and it was over all a very enjoyable experience. One thing I noticed was that you couldn't get back from the place you teleported to through the teleporter, instead you had to die. Other than that I found no bugs and the game ran smoothly :D

I don't know if you've heard of Game Development World Championship before (gdwc2019) but it's a competition for indie game developers where they can submit their games and it's free! It's great if you want some more visibility for the game and it only takes a couple of minutes to join :)
