This game is lacking a lot of polish. The controller controls have no dead zone so you can't just move up/down/left/right without wavering like you're drunk. Every time you press start on controller, the mouse cursor is hovering over the middle option. The default mouse sensitivity is like 0.5 dpi and the input menus to change it lag like crazy.
Gameplay wise, there's multiple death pits you can't even see, and most of my deaths were from falling into them, or veering into pits due to the analog controls. The unmarked camera turns also sometimes just throw you off of cliffs. Level 4 was genuinely a bad time due to this. In the last level, after falling down a required pit, I took a sidepath and started progressing through the level backwards and ended up at the start of an alternate path or something.
Pretty much every level ending cutscene had my character running in place. One time the cutscene ended and the boss did another attack before it transitioned to a new level. Level 5 also has a pit under the reused core boss where you can't escape and have to restart checkpoint.
