I've only played 2 or 3 levels and seen bits and pieces of the rest, but my impressions so far are: it's genuinely really interesting. It feels like an evolution of obnoxiously-difficult Amiga "eurojank" platformers, with the greater resolution, addition of continues, and addition of a health bar making it feel like more of a fair challenge. It has some rough spots for sure (it'd probably be better if you had invincibility frames, and the final level looks like it'd be miserable to play with that graphical effect), but it seems like a decent game. I wish Team Hoi had better luck with publishers so we could see further evolutions of this, because I feel like it would've been a distinctly different vibe than most other 2D platformers.
