if you make a number 2 for this game make sure you change it so if the end guy is eaten the monster cant continue to eat everyone down the line without them shooting at it. It happened to me and didnt even notice till half my guys were dead.
I have to say i do like this game, even when i die by the same spike every time! I do think that you should not have put checkpoints every 10 feet, it makes it to easy. But i give it a 4/5.
If a level is to hard then see what shape it mostly has, then reset all of your upgrades and upgrade that shape!!!(reseting upgrades gives you all your points back!!)
