should the Squirrels not disappear?

Really cool idea! I echo the other comments and think this could be expanded a lot.

Let the bodies hit the floor!! I loved the idea behind this game, and I was absolutely shredding in the arena. In fact, I was going so berserk that I often found myself buried under the dead corpses of my enemies, and unable to move. That was hella fun! Great job on this!

Love the premise. Being able to fight/possess new animals with new attack patterns I think would be a logical next step.

 I found that the dead bodies having collision made it really hard to move, especially when big waves of squirrels were attacking. I think making bodies fall behind alive entities would make the game much easier to play.

There was no cooldown on attacking, so I found that if I mashed fast enough, I could instantly kill enemies. Maybe add a cooldown to attacking? Especially if there are more animals with more abilities.

Overall, the concept of keeping dead bodies around to repossess was super fun. Great job! Would love to see this expanded!

The idea is great! i wish there was more content, like enemy and attack types. Despite being simple the combat system feels fun)
