Platformer X vampire survivors is pretty unique and pretty fun! though there are some problems with the inputs. idk if its my PC/browser causing it, but there is a noticeable input lag on movement inputs specifically the shooting and "beast mode" mouse controls is fine.
for the game itself, it starts out a bit too slow because the health scaling is a bit too much to handle early and a bit too easy late(even without +basic attack damage) and some of the upgrades are a bit lackluster so it really depends on RNG if the game will be fun and engaging or boring and grindy
overall its pretty nice!
