Thanks for the feedback and playing the game!
Yeah balancing is a hard act. I need to get people to playtest it, but I guess that is part of the rating in the jam.
I was thinking of making the rotation speed also be attached to the amount of tentacles you have. That would make it actually better in that case if you spin in place. Didn't think of that! :D Spiky tentacles do break after few hits though so at least I tried :D
