Thanks for your suggestions! :)
- Yep, I totally agree with that.
- I experienced the same issue recently and saw it in some of the other comments too. I will work on a fix.
- What do you mean by that exactly? The text like “Damage +1”, “Speed +1” isn’t enough for you? I’m planning to add some “tooltip” feature when hovering over things, e.g. the different ball options top-left. Perhaps I will add something for the upgrades, too.
