I absolutely love the concept behind the game, but it feels a bit flat in execution. I think the idea of using a healing as a way of dealing damage is fun in most games, but it's not really a healing wave if there's nothing to heal and the only thing it's doing is damage, is it? I do love the "upside/downside" style of upgrades, though the game is easy enough (especially due to enemy navigation funneling them into straight lines by the end) that I'm not too sure how impactful my choices really were.

Surprisingly enjoyable! My healing wave basically turned into an uzi by the end. Balancing out the pros and cons of upgrades made for some nice push and pull. I loved the end of each round where the stupid skeletons all lined up to die hehe. I'm just gonna share what I hoped this game was going to turn into but it never did - Paladin knight allies versus these undead - where you have to carefully heal your allies while also blasting the undead hordes back. Just an idea, I suppose.

Cool game. Fits the theme. At the end of the round, the enemies become grouped parallel to each other and it becomes easy to finish them. Could be even better with more consistent  graphics

Ok so the game is good, but needs a lot more polish:
In the graphical side: The game felt empty, the assets pixel ratio don't match so it feels asset swapped, ex: The ground compared to the player, but the UI was rly cool, the camera was really zoomed out on a small character, this also can be a mechanical flaw.

In the mechanics side: The game was not well balanced, in wave 1 I got a lot of enemies at once, to improve this, maybe instead of quantity, you might increase their damage, or more complex AI (but that will take more time), the upgrades were a bit also unbalanced based on how many enemies spawn each wave.

In audio: There sadly weren't any audio, but this game could had cool music each wave!

For the theme: I think it fits it quite well.

Overall, this game was pretty cool, I rly wanna see you improve on it

I like the upgrades. Every level can be played differently. 

nice customization options on the attack.

Heyo I just played your game! Love the vampire survivors feel! The upgrades after each round are pretty cool, and I like how you incorporated arc width AND range, not just one of those. The enemy AI had interesting movement where eventually into the round they all just line up parallel with my character. This unfortunately made the game really easy since I could just stand still and the enemies would walk at me from one direction. Overall though, fun game!
