Hello from xk discord. Nice first try, there is lack of music effect. And I don't know, how I die on boss, when I have around 65% hp. I think, it will be better, if main hero don't collide with enemies and if it was infinity map with camera centred on hero, like vampire survivals.

This fits the theme perfectly

I like the concept a lot. That said, the collision on enemies with so many around make navigating particularly difficult, and not having an invincibility frames also makes getting hit rather punishing. I definitely think it would benefit from some balancing, as well as adding some receptivity to the player's actions, like indicating if an enemy got hit, whether that be through a new animation or a health bar for an enemy combatant. I also noticed on full screen the level only occupied about half of my screen. Other than that, I think it shows a lot of promise. Solid work!

Too bad there's no screen resolution adjustment forcing me to play in wrong resolution.
Regardless, the idea is good but it needs rebalancing and fixing to make it better.
