the wave effects makes the game harder
some sounds could make it better
the graphics looks good but the character is blur
bug : and i got stuck at a floating island and when i tryied to escape i just respawned
i don't know if unreal engine is good for a 2d game
but the concept is interesting
you definedly needed more time. But after the game jam you can continue this game and maybe it'S will be a hit
good luck for the future
