All devs need to do is do more co-op stuff like that one mode in Alpha 3. I find my friends new to the genre often feel overwhelmed trying to learn how to play the game while in the middle of a 1v1 and get frustrated either way if you take it easy or wail on them. Co-op against an AI would help with that, even if it's kinda jank. Could even have a mode where you play the 1 in the 2v1 for more skilled players.
