Good game, though there is a bug where the game does not remember that you played the tutorial or the first battle of a campaign, so when I tried to play the second battle of a campaign, the game locks me out of it and tells me to play the first battle first, even though I already did it.

The hotfix is up! Battles now count once you've played them for a few minutes, even if you leave before the end. If the game still forgets your progress, your browser may be blocking saves from games on itch.io: signing in with Google (click profile, then scroll all the way down) will keep everything in the cloud. Thanks again for reporting it!
