Much appreciated! Pretty chuffed with the banner myself :)
Yeah, I think average playtime is about 40 sec - 1min, so short is right on point, haha. I think I could have done a bit more balancing, or maybe a gradual increase in difficulty. So hard to tell sometimes when you design it 'cause you play it over and over and can't tell what's difficult or not anymore.
Thanks for feedback and playing!
