It sounds like spike like's spawn rate needs to be nerfed; I will get on that.
Only 1 Jellyfish spawns at a time... it will hunt you down... but maybe it needs a speed increase.
I will add in a system that will reduce the lag of the rainbow pill based on your fps... this will make it less intense and... will save your gpu in the long run.
I am glad crashes have stopped... I can't believe I let them slip through!
