Visuals are well done, but gameplay is very repetitive. You really just spam the same attack over and over, making it hard to care about the rules changes, so you kind of just hope for the best.
I think if damage was balanced (which it's not atm) then gameplay won't feel repetitive.
Also, the eyeballs are the only ranged enemy. And if there's more of them, it could create more variety.
The rule changes could also be tweaked to increase impact.
