Another one of these? What's the point of developers thinking up of original ideas for their games when they can just recycle crap from other games to get 4+ stars?
At first this game looked very poor. But then I realized that the game has decent depth to it with the bullet shop, upgrading the rocket, changing the location of firework show, viewing your show and etc. Maybe include a instruction manual of sort so beginners know what they're playing and what to do. Also, you should really explain what each bullet does. The concept is good and the game is also, albeit very rough on the edges and lacking direction/instruction.
I wish I could build a game this good with Unity.. I've been tryna use the program lately but damn is it hard to know what I'm doing when I have zero programming experience D:
