Not sure if this game is still being worked on. But I would like to add the count down timer feels too restrict at the moment. Usually Beat'em Up game would have the timer refresh back to 99 after every major group of enemies (as in the stage could be moved again). But this game only refresh timer when the player dies. So I would die from the time run out before my health does.
It's fine for the demo since demo give infinite continues, but I imagine this get really annoyed once the full release version come out.
Also... the hit box can feel a bit of wonky at times when enemies would merge with my characters. Usually in Beat'em Up this is a none issue since character merging together would result in a grab (either by the player or the enemies), but I had more than a few instance where the enemy ends up standing together with my character where I can't hit them standing still, and I would just have to take the hit as I move away.
