I like that I don't need Star Gems to play for as long as I want, but there are a *lot* of buttons that take them. Asking confirmation to spend gems would be nice, at least for the stat boosts on the level-up screen. Oops.
NEW FACTORYBALLS GAME YAY. *ahem* I do prefer the pure color/structural tools from this and the last one to the weird stuff in FB2. Also, next time, can we please have the tools as well as the paint buckets for the ending?
