Hi, there seems to be a problem with the web and downloadable versions of your game, as no matter which way I turn the first switch, the corresponding gate will not open, unlike what was shown in the video in the comments :p
Hi egor, I managed to finish the game, thanks to your update :)
I liked the fact that even though there are only 2 types of creatures and 1 boss creature to fight, you managed to make each encounter varied, and that maze near the end was quite mind-bending to make my way through, making it satisfying when I found the correct path :)
The music was simple and nice, plus it matched the pixellated atmosphere rather well :D
Thank you for letting me play your game, and I look forward to playing more of your games in the future :)
