Yeah... we relied on the UE4 physics system for all the jumping, swinging, and hook throwing which works at 120 FPS, but gets weird at different framerates (for example, if you switch to windowed and are no longer bound to your monitor's refresh rate). I made some fixes to stabilize the physics on different machines, but those aren't in the jam build. I'll be posting the new build once Jam deliberations are over and I can post updates again.
If you're curious, you can download the newer build here:

I'm curious if the fixes I put in actually improve the hook physics for you.
