Sadly I don't usually play these jam games with others around, but I still gave this one a shot and acted like both players haha
I like the graphic style and UI and controls. The music and sound is also decent for the game. The power-ups are very cool too, especially the swinging bar and the bullets. I found out the bullets hurt yourself also if you run into them! Which makes sense actually.
The only thing that I couldn't figure out is that the attack button never did anything for me during the fighting part. I ended up having to use the swinging bar to defeat the other player.
Also in the store it seemed I was able to buy everything even though I didn't have enough money collected to do that yet.
Solid entry!
