Nice work, I need to play some more but initial thoughts are
+ Movement is good,
+ Shooting and the UI is self explanatory
+ Progression pace is good
- Hard to see the platforms
- despite a lot of health re gen perks dying is very easy
- sound effects on the shooting can stack and get on the loud side
Bugs
I noticed I would often get gifted a triple jump without needing to unlock it.
I'll play more later, but yeah. well done!
