Tried to get all the cups, but I was missing the Spring Cup... so I went to look for it and it doesn't exist, there's just an "Undefined Cup" around springtime that is probably it :(
Also, with the 10% Power thing I 1-hit each boss for like 4,600 damage or something, maybe the maths is a bit off on that?
Cool game for a while, but this isn't "strategy"... to win you HAVE to juggle and although that takes skill it isn't the same skill as a really great tower defense game like "Protector" or "GemCraft". What is really a shame is that with a couple of tweaks (make selling towers harder and creeps weaker) this could be MUCH, MUCH better.
