Complicated!
Gameplay wise this was pretty hard to grasp. I found the mechanics to be fun, but it was very poorly explained and I am still not entirely sure if I was playing the game correctly. The game gets overwhelming very quickly and while I understand why you went for that for a vampire survivors game like this, but the projectiles being fired at me were pretty hard to see, and combined with the excessively large UI, it caused me to take damage and die to things I couldn't see and it felt unfair. The game itself is fun, but there are some unfair elements to it, that make it feel frustrating at times.
Visually, the sprites and effects are all pretty good, but like mentioned previously, the hard to see bullets and large UI hindered the visuals a lot.
The audio was good but a bit loud. Also I got a notable audio bug. I set my SFX and Music Volumes to 25% and when I died and returned to the menu, the volume got reset to max, but the slider still said 25%.
The theme interpretation was frankly just confusing to me, and I didn't understand it.
I think the core of this game is great, but there is a lack of polish here. I will say that if it was there, this could genuinely be a steam release.
