Incredible entry, a really fresh take on a survivor like. Full marks for originality. Though, with limited ability improvements and only 10 waves, combined with the boss fights, it felt more like a bullet hell most of the time. But the downscaling was handled very well, readability was  great, abilities were straightforward and easy to understand.  UI was presented nicely. Overall, really nice work.

I’ve never played a *Vampire Survivors*-style game quite like this before. It’s a really interesting concept. As a potential mechanic, you could also add randomized color palettes for the pixels

Uplifting beat. The game is cute and I can immediately figure out how to play it at the first glance.
the economics has some balance issue. To trigger a bankrupt and resolution degrading, I have to intentionally purchase all the 6 items every level (by using the reroll feature after purchasing the first three). 
I think the reason is that the resolution scales to the square root of pixel number. So at first a small purchase almost not change the resolution. 
Another idea is to add the debt system, I guess.
If one fixes this issue this will be a very brilliant game.
Also I do find it funnier to play in an extremely low resolution settings.

A truly original idea(at least in my opinion).If I could give 6 stars on that, i would. I was surprised, love it
