This game is absolutely a rage game to me.
I am going to show great restraint by not taking out my frustrations of this game. This is actually a decent little game and feels like a typical flash game. It is fun! My only actual complaint is that the explosions do not actually kill the spiders if it only touches their legs, which lead to a lot of frustration.
As for my own sanity, holy god did I hate dealing with specifically the spiders. That bug I mentioned made me want to bang my head through my monitor out of frustration as the shot would go, explode, and hit their leg. Which in fairness to my insane rage I did complete all 13 levels!
Overall this is actually a decent little game, but it did make me wanna die just a tad bit. Congratz!
