Hi Petanek!
I just finished playing your game, and I had quite a bit of fun! This game was really hard, but I had fun playing! I unfortunately couldn't reach the end (If there even is one :P). I can tell you just used the default unity ui graphics, but it's fine! It works. The music was nice at first, but got VERY repetitive over time. I loved how the player you played as was a pair of eyes :)
Overall, I had quite a bit of fun with this game and I really do believe this has tons of potential. Perhaps if you had added a health bar for the player, it would have made the game much easier and I might've be able to finish it then. Fun submission, well done! :D
