Thanks for the feedback!
Yeah, I'll admit I didn't think the whole inflating mechanics through. I'll tweak the numbers a bit to give players better control over movement when inflated and make the platforming part a bit more varied (might let players knock things back with the inflating ability while I'm at it) soon.
Also, side question, on a scale from 0 to 10, how bad/good of an idea would it be to let players actually attack the squares (outright shoot "air" pellets whenever they go from being inflated back to normal, or just launch some part of the slime to slow things down)?
