I played it! It was really cool!
That is cool! I still haven't figured out how long the demo is because I keep dying in the desert. I really enjoy the game though, I try to maximize coins in the first levels. It quickly becomes overwhelming depending on where and how far from you the enemies spawn but I think I'm still improving. :)
I'm definitely going to reduce the difficulty at least a bit. I'm probably going to start rounding up some playtesters soon. If you'd be interested in playing more of the game early to help with game balancing and minor bug hunting, join the Discord server linked in the game page (that's where i'll be hosting playtesting). If you'd rather just wait for the game to be done and good, then that's fine as well :)
