started coasting and got to level 40 just skipping upgrades
Thanks for playing! I've made the game less generous with money, early & late game might be more difficult now
pretty fun but the economy of the game feels kinda wack. getting shiny core on a banker ball or fusing a banker ball with a sniper ball will instantly get you more money than you know what to do with.
Yeah, just playtested (got stuck playing for like 3 hours trying to spend all that cash) after my last release and realised I need a lot of adjustments, will further balance it tomorrow. Thanks for playing and giving feedback, i appreciate it!
Bug found. When you get 50 balls and choose an upgrade to copy or duplicate - the game is over. Fun until then though. Being able to take out a boss after a couple of seconds and the massive number of upgrades I think are the highlights.
Thank you so much for playing it! I will fix the bug soon.
I’m still working to add even more ball types/upgrades and modifiers, as well as artifacts that affect the gameplay globally.
