Hi there ! So I haven't played until the end of the demo (well, I guess I didn't went far).
The game has potential like the user interface is minimalist yet great, some feedbacks are great and the visuals are fine.
But as it is a demo, it does feel unpolished at several level : sound design, "tightness" in some game feel (like for the dash), the enemies frame of attack is not always readable...
But overall there's definetly something in this game, good work for what has been done and keep it up for playtests and so on :)
