This game feels just like a prototype rather than a full project. That's not to say there weren't some good ideas. I appreciate the way you use your echolocation and had fun navigating around the tunnels. With a little bit of art or just a color palette change, along with some polish, I think it could be a lot better. The echolocation sound it really annoying though, especially when used repeatedly. I personally think that the simplistic art style would have worked a lot better had you not used the pixel art bat. Overall, it has some good ideas and decent execution, just needed a little bit more time and care. Hope to see you next round!
