Ok I found my favorite game of the jam. This is crazy work, especially for the art. Making and assembling all of that is amazing in 4 days. For the gameplay, I also struggled with understanding the stun mechanic. Something else is that most of the time I feel the attack choice is solely determined by picking up the right lane. Like, you have all those mechanics interacting with the different attacks, like the stun possibility, the attack order, the HP management. But in the end, if the lane I'm on get targetted, I'm just gonna pick the one attack that gets me out of the way. I think that's something to look out for if you continue working on the game.
I entered the gmtk this year as an artist to do the art direction on a game so that I could use it as a portfolio piece, so let me tell you that your artist can be proud. Have you made all the art digitally? I wish I'd been able to do something that impressive. Btw please check out my game if you find the time ;)
