It's a good idea, but it feels very unfinished. The level is walled in which looks very strange, and there isn't a lot of sound which makes it kind of boring to play. It's definitely a learning project for the developer, so I'll give them the benefit of the doubt, but I think they definitely could update this to improve the level design at least. I'd also suggest adding some music and other sounds to the game as well if you do update it.
