It would be better if the shooting widget would change its colour to e.g. blue and when it is ready to shoot again it turns e.g. yellow, because it's hard to see whether it can shoot or not.
Thanks a lot for making this game and posting it on kongregate. I hated this game "Motherload" where the programm says such stupid things like "Goldium" everytime you dig out gold. (you can say gold or aurum; but not goldium)
hmm not bad...
