Doesn't have much of an NES feel with the way parallax works here, not to mention the amount of sprites on screen or the sizes.
Felt alright though, very flashy, and I enjoyed the intro cutscene.
Not too much in terms of gameplay, kinda just moving around and trying not to stand in place long enough to get hit, wish there was a bit more to it. But I've never seen the appeal to number go up games like Vampire Survivors, so maybe I'm just the wrong audience for it. Not really sure how to improve it, feels like enemies either smack you occassionally or might as well not even be there.
Took me a while to realize the different buffs were replacing my current stacks instead of adding effects onto it, which was a bit unintuitive and didn't feel great. Ended up grabbed by a big guy and beaten up by the gang of green flying ones from full health, so...RIP
Character and enemy designs were pretty cool though.
