I got killed instantly after the role changes. Like... 8 times out of 10. That's gamebreaking.
For the rest, I really, really, loved how smooth the game is. The movements are fine-tuned and super easy to learn. Also, I'd like to be allowed to use a button to restart the game instead of having to grab my mouse every time to click on "restart".
I wasn't able to use the upgrades.
Very cool game, thank you !
