--Bugs (Pun not intended)--
Mite is invincible in V12 (Is the Spider?)
Mite changes colors
--To Fix--
Make the mite's color-changing optional
Make the mite killable again
Spider needs movement animation
Spider is too fast
Spider is too strong
New jump sound for the bugs
New death sound for the bugs (Regular zombie death, but in 0.2 timescale? That sounds pretty good for a dying bug)
