The game felt quite nice at first, and I was really eager to find out how it will develop, but I encountered some issues.
First of all, the button sizes in menu are somewhat off, often clicking on the bottom half of play button I would just quit the game. Secondly at some point while fighting the skeleton archer in the first area, I just teleported under the floor? I am unsure what happened. Then in the second area FPS tanks quite a bit, tho it gets more stable after a while. And lastly I just couldn't figure out how to use ice arrow that I got. I tried everything for a couple minutes but it feels like I can't progress further.
All in all, I think the idea seems nice, and honestly the artstyle although quite simple, works well. With a couple adjustments it could turn into a really nice game. Good job!
