Trampoline
EIDT: oh right, 3.3 only
Description: The floor is bouncy.
Try to put force into your landing, or else you won't go very high.
Settings are built into the file.
If you make your own settings, either set the dm threshold very high, or turn dm off, or else when you bounce, you'll die.
I declare this the unofficial mod of the clan BNCY, even though i've never known a member of that clan.
