Hey! Thank you for taking the time to play and leave your honest feedback. You're completely right—since this was a 48-hour jam, I focused entirely on making a simple, bug-free arcade loop with tight controls rather than trying to build a massive upgrade or progression system. I can definitely see how it can feel barebones if you're looking for more depth! I'm planning to expand the mechanics and progression post-jam, so I'll definitely keep your notes on upgrade potential in mind. Thanks for reviewing!
