So, there's a lot left to be improved here.
For one, it does not feel great to move around. The acceleration is super weird and you basically don't get any midair control. The game's level design is confusing at best.
The graphics look super blurry, which is something you do not want for pixel art, though that might be Unreal Engine's fault, no clue :/
It'd also be nice if you optimized loading times more, the game takes far too much time to load/reload.
Additionally, the little voice messages are very unnerving, and you could've focused your time elsewhere(i.e. making the map more metroidvania-like and building points of interest).
Good luck on your next game projects!
