Heya, thank you for the feedback! I believe we have it set so if your wallet is maxed out it deals 20 damage to enemies instead of 10, not that it's super noticeable to being with. We did kick around the idea for more money doing more damage in a sort of scaling way, but we never did implement it fully. As for the speed decrease/wallet cap, we wanted to nudge the player to remind them to spend their money, be it on upgrades or going back and smacking the boss a bit, or provide a challenge for people not wanting to hit their cap while trying to get to a shop or a level exit. There are plenty of different ways we could have handled this aspect, and we definitely should have tweaked and playtested a little bit more to fine-tune what we wanted.

Heya, thanks for trying it out! That's completely fair, all of us were learning how Godot 4 specifically works in comparison to Godot 3, and we did spend up to the last minute working on stuff, so bugs inevitably slipped through the cracks. Playing through a bit before pushing a tiny update, I did notice our player's animations lock up after interacting with the shop in one level, but I wasn't able to consistently get it to happen enough to pinpoint a definitive fix yet, but it's definitely something for us to investigate. 

Heya, thank you for trying the game out! I'm glad you enjoyed the concept, it's been an idea I've been sitting on for a long while now, and I'm happy to finally present it in some way! I'll admit balancing the dragon's health was a big concern as I'm not too well versed on fine-tuning game balance, and wasn't entirely sure how much health would have been too much. In retrospect I should have focused it more around the maximum multiplier amount and made the final grind less cumbersome, rather than set it at some arbitrarily large number and leaving it at that. I'm still trying to figure stuff out about resolution so I'll likely update this with some better options once I figure all that out (that's likely also why expanding the window makes stuff like the UI seem more lumped closer to the left side than more evenly spaced out). I did push a tiny update to hopefully fix at least one crash issue (turns out one level not having a player spawn location kind of messes with respawns lol) and knock the boss's health down to a hopefully less tedious amount and more generous regen timer.
