Ughm, I wish I could play this game, but my laptop doesn't handle UE4 very well, so I had 0.5 - 3fps.
Everything else is really good, the music, the graphics. Judging by the gif it plays pretty fun. Just if you can optimize it somehow, please do, I really want to play the game.
Yeah UE4 is pretty heavy. I could try to optimize but I don't think it would help you in your case, the game is actually running in full 3D behind the scene with extra filters applied to make everything behave like sprites. I am also running multiple fluid simulations for the water which can be pretty heavy.
