I think this is one of the best Construct Creations I've seen so far. It's real fun. Could need a little more gameplay though, maybe extras or other things you can shoot or build up in order to get through a level. Maybe you could add an option where there'd be a limit of boxes you could use in a level to get through it - right now you can simply blast away boxes and getting throgh the level is a safe bet that way. It's no challenge.
Also, the drawings are sometimes really off - like, in the first cutscene, when you suddenly see the guys eye - that looked really weird.
Other than that, this is really cool.
Maybe we should create a thread where all the finished Construct Games are listed and sorted / updated dynamically?
