I have to say the game is fun; it’s clearly inspired by *Vampire Survivors* in terms of mechanics, but these have been interpreted differently—or rather, evolved. I liked the upgrades you chose—they make a lot of sense (which isn't always a given). Overall, it’s a solid, well-made game.
On the downside: the graphics are perhaps a bit too simple and flat, and there’s no magnetism at all when it comes to collecting the XP gems.
