Really cool idea!
The art style is really good, the simplicity really works well here. It's simple but entertaining. The survival aspect of it is very interesting! The combat design could use some different mechanics. It's difficult to hit an enemy without getting hit for example, and when enemies start piling up it gets impossible. Dashes, blocking, or stuns could work well here. Especially since enemies appear pretty early on, and if you're not super quick you won't have what you need. With better combat you could face more enemies and lengthen your run.
I did find it quite hard to play! I liked the challenge. However, I have to say that it's easy to outrun your enemies. You can't do anything else, but you stay alive. Though this is hardly the best for gameplay.
Loved it! Liked it a lot <3
