Really great idea hah. Currently it feels as a hard as getting to the gym everyday, so I can't say I felt overpowered. If the intention is rage bait, then its definitely successful, hah!
That being said, I do think there could be a version of this that has a gentler intro, especially letting the player get accustomed to the controls before sending in those damn shooting enemies. Also perhaps starting with enemies who are a bit weaker so you can crush those puny dorks with yr huge muscles while getting accustomed to the challenging controls? Anyway, nice work, very funny.
