Nice Plugin, i like it very much.
As I had the MOD running for some days now I was able to spot some bugs.
1. When the speedup-pup has worn up the speed seems to be a bit too fast, so when you're creeping you still hear footsteps.
2. If you manage to get the speedup-pup at the end of a round, at the beginning of the next round you can immediately start running with speedup (ignoring the buytime). Well as of now I'm considering this a feature rather than a bug, but thinking seriously about it, it's a bug.
3. After getting the HP-Upgrade 2 times and then the 2-HP-per-Sec-pup i noticed that the counter goes 250, 252, 254, 2, 4 and so on. You're pretty shocked when you see those little numbers after getting all those nice power-ups.
I'm not sure if you really have got 2hp after the counter overflows. At least once my brother told me that after getting all those pups mentioned he had about 4hp (still raising) and got hit by a grenade and wasn't dead so it was probably 254hp + x.
