Glad to hear you liked it! I'm definitely planning on adding art & animations along with sfx & music, along with a fleshed out single-player mode. What I have in mind right now is a very hard turn away from the current prototyping assets, so once stuff close to the final art assets are in it'll feel a lot different. But right now I'm just focusing on really polishing up the movement since it'll be so core to the game.
