Massively fun game. A problem though, the cursor keep flying out of the game screen making traveling to the edges of the arena impossible. A solution I've seen is locking the cursor to the game border "Itch.io now has control of your cursor".
Also I'd recommend providing the download for the game here on Itch as people are more likely to download it here than for a private launcher like steam.
Anyway. I'm really looking forward to the full release ^_^
