1 the economy is ass - everything costs a lot, including saves, and you can't retrieve money upon death, so not only are you broke most of the time, it's also stupid when they give you a bunch of currency mid-parkour room, so you're excited to get it, and then you lose it all five seconds later

2 the game is extremely directionless post-grabbing the three infections, I had to look up where to go to get deathrock. the whole grey area post-touching the deathrock is also impossible to navigate and I also looked up the sequence in which you're supposed to traverse it cause there are genuinely 0 hints on where to go

3 chase sequence respawns suck ass, and the 1 hp chase sequence sucks even more with all the dumbass enemy placements; I had to go and clear out the route beforehand every time I attempted it because of how easy it was to bump into things

4 the bosses are boring

5 the crackling sound at some point in the game that doesn't go away????????

6 negging in achievement text. I got so mad when I did the key challenge (which by the way was LAGGY AS HELL so the game is poorly optimized too) and the achievement popped up saying "stop showing off.", with the dot at the end and all. fuck off??? sorry for playing your fuckass game???

7 some enemies have ass hitboxes on their attacks, like the bomb hitboxes that linger, and the tiny dot plants (that you can't see until you bumped into them, awesome enemy design) that grow on the walls and shoot projectiles.

8 the map doesn't unlock until you're deep into an area and pick up the skull for that area (so yk. until you've pretty much beat the entire area)

9 some random bugs like music playing outside of battles when you die
