As a concept it's pretty good how it is. Anything you add next would depend on your audience (aside from just more levels I mean). For me, I would add a story intro and some dialog between levels, and a home base (pocket dimension?) where you can do cozy farming and display achievements. And of course multiplayer. :rofl:
hey man, I meant to reply to this sooner but got carried away with things, but yeah, I really like those ideas and so far, this is my favorite out of the games and prototypes I have made. I think this is one worth revisiting and expanding into a bigger game at some point. Thanks again for letting me know what you thought about it man!
