Thanks for this great review!
1. This game is still being developed. Lots of things – including bugs – will be changed. For now, it’s just a prototype.
2. I’ve already heard about that typo, but I’m going to fix it in the next major update.
3. Leveling up gives you loads of cash – that’s all for now.
4. As you said – the reason the bar resets to full is precisely because the opponent’s health is below 1. It doesn’t affect the gameplay too much, but of course it will be fixed.
5. Upgrading the coins means they not only appear more quickly but are also worth more.
I hope you enjoyed playing the prototype! Btw: I’d love to see it on VOD!!
