In the first match (tutorial) the game asks you to block attacks, but it will never finish (I'm blocking attacks for 5 minutes).

10/10 will buy. Very fun, could definitely see myself even playing some sort of endless mode in this. That being said: please do keep the campaign it was very enjoyable. Think this will be a banger on the steamdeck too, the oled should handle the artstyle swimmingly. Will perhaps try out later on the device. So far PC experience has been great. 1440p or 4k support would be nice too (but using 1080 was aight, for a demo at least)...
