its so laggy

Its pretty boring because you have no options. You should have taken the whole clicker part of the game out because clicking and clicking is boring and annoying. Its a pretty good concept though. But its not a good execution.

For a scratch game its fine but its very buggy. Sometimes you shoot the wrong way than where you are pointing. It can be fun at times but most of the time it is boring and really easy. I think if your gun points to where your mouse points and the movement was more smooth it can be better. Scratch can be annoying at times though and its hard to make smooth movement. I suggest using construct 3 because its easier to make games and export. Also construct 3 can be used online without having to download it.
