Hey there, thanks so much for playing and for the awesome feedback! I'm thrilled to hear you found the game beautiful; that means a lot to us. You're absolutely right about the character animations needing some work; that's definitely something we'll focus on going forward.
Regarding your experience with upgrades and difficulty scaling, it's clear we need to reassess the balance there. We've also become aware of a bug where upgrades carry over when restarting, which wasn't intended. So fixing these kinds of issues and better balancing our game is a priority.
Hearing you say you'd pay for a fleshed-out version is truly motivating! I'm glad you had fun overall. Thanks again for playing!
