@einfach (and i guess @ the developer) maybe the number keys would be put to good use if you could assign them to your abilities, that way you could use up to 10 abilities in a short time. It's too hard to click and go back, especially if you need dartling gunners attacking the bloons. Please consider allowing # hotkey assignment for abilities.
here's what i don't get: B.B. wanted a midnight snack, so he had to get his wallet which was stolen by the gummies. Why doesn't he just eat the gummies? There seems to be an unlimited supply. Also, how would the gummies' money be acceptable in the convenience store in the real world? I hope they have a cash register with a "mega sized purple diamond ring/bling" slot.
A wau to makw it better: make all the 1 point nallons various colors, like some red, others blue, some green and purple, (you get it). Make 5 ballons grey and shony and aller than the normal ones.
