An Idea for Zac's Chunks
How about whenever Zac picks up one of his chunks, he gains a small, short-lived speed boost? This would make his chasing ability more viable while still being able to collect his chunks, and it would offset the detours he has to make to pick up chunks. Also, he would be rewarded more for chaining chunks together, since the speed boost would be on him more constantly, and he could prevent enemies from stepping on them more easily.
I don't know, what do you think?
