TLDR: yep, its playable and finishable little platformer, unpolished, but good.
Hello. DIsclaimer:
I do understand this is your first steps, so dont take comment as offense, instead, treat it as a list of things to look into on the next update \ project.
Graphics are not good. Cant see shit indoors. Too much "reflective metal" surfaces and not enough of actual colored surfaces?
AnimBP is not set up. Pawn isnt rotating properly. This results in boost(E) boosting player in random direction, instead of desired one.
This is not accepted behavior for precision platforming game.
Camera attached to waist, not shoulders level means camera gets waist level and into characer when standing close to an obstacle.
Disappearing / transparent character model usually is used for this.
Interact icons are unreliable,they do not response properly every time when i tried to interact.
Having a limited supply of something(oxygen cans) and respawning player in a level instead of respawning everything else aswell - is no good. its a way to get player softlocked quite easily.
Thank you for your time and good luck with gamedev journeys.
