Description was a little hard to read, but it does sound sort of interesting, I'll try it now.
Alright, it's...decent, still needs a few changes. I suggest adding 50 health per lvl(little goblin guys level) and making the tome in the shop cost more but give 100 health. I forgot to check to see if the boots stacked but if they do I would try to make it to where they can only have a max of two or three. I also think there needs to be some sort of dumbfire rocket or something. Add a burn effect to the suicide bomber, ranging from slight dmg on the outside to moderate to heavy fire dmg in or near the center. Im also unsure if the stasis traps were supposed to get the goblin bombadiers or not, but I think they should, and speaking of the bombadiers, give them a detonate ability.
T'would be about all I have right now.
