The platforming parts in some levels are insane. Even the combat isn't a cakewalk as the enemies do huge damage and the player hitbox is way too big.

Thankfully they've since fixed the player collision. But yeah, the game can be tough. Often times you gotta be methodical so you don't run out of ammo or get torn to shreds in a room full of cat ladies.
And at least the platforming controls aren't terrible; the OG developers did that much for us :D

They could rework the drop RNG a little bit but apart from that, the game is not that difficult.

But funnily enough, the final boss is a cakewalk
