I'm talking about some unpolished details, it's nothing gamebreaking though. Some notable ones I remembered:
- It's possible to pick the Hard option in the difficulty menu without making it highlight if you do it fast enough (https://my.mixtape.moe/ejrkvk.webm)
- Player appears to be able to shoot for one frame after a death after they're warped to their respawn (https://my.mixtape.moe/untqzu.webm)
- The fuel bar visibly goes past the limit for a frame when you pick up the item (https://my.mixtape.moe/jdetya.webm)
Regarding the boost button, I suggested making it just boost you in whatever direction you're facing if you're not holding left/right.
