I'm glad you enjoyed the game's visuals and music. I'll definitely consider adding a volume controller in a future update to give players more control over the audio.
Regarding the shop, that's a great point, and I'll work on improving its behavior in windowed mode.
I appreciate the suggestion about the cursor hotspot and will look into it.

Haha, who knows! In future versions, they might surprise you.
Thank you for playing and leaving your feedback!
