Thank you for your feedback!
- I'm quite new to game development overall, and this was my first time working with user interfaces. Since the initial release (and even before), I've been actively trying to fix UI-related bugs. I thought I had addressed everything, but apparently, I haven't. I'll look into that and release a patch as soon as possible. 😊
- I'm not entirely sure I understand what you meant here.
- This was actually a deliberate design decision. By making both gold and tower placement decisions more significant, players are encouraged to carefully consider their choices before placing a tower.
