Read the original on Steam ↗Small patch for now. The upgrades were supposed to appear in the next major update but that's gonna take a long time so I said "Screw it" and decided to add them in now. They only appear in difficulties under Expert, and have a 1/10 chance of appearing in a level, replacing a random ammo crate.
The list includes:
Speed Boost
Infinite Ammo
Infinite Shocker energy
Invulnerability (Basically just Mario's Starman)
You can see an example of one of them in action here.

I've also improved the wall jump physics by increasing the height they give you, and I also lowered the wall slide gravity. I'm also considering just removing it entirely so the wall-slide just becomes a wall-run but we'll see.
Various bugs have also been fixed, mainly the Dimension time being counted even during cutscenes. Oh yeah, and I added a screenshake slider.
