Thank you for playing! It's always pretty surreal to see a stranger actually playing something I made. That's pretty cool of you to take the time to record yourself playing through all of the games in the jam. I'm sure a lot of devs (Myself included) really appreciate that.
I actually had in my notes to add a popup telling you what button to press to attack! But I just forgot to include it. I think maybe I was waiting until I implemented control remapping so that I'd show what key you've bound it to? Regardless it got left out, so it sucks that you had that moment of confusion where you didn't know what to do- that should never happen in a tutorial lol.
Thank you again for playing!
