here is somthing epic to add - medic class where you can heal yourself over-time by rapidly pressing space and you get a medic's dual pistols witch removes pistols and replaces pistols with the duel pistols plus add more enemies like robot rubber and sharp pencil
add a thing where you can switch the weapons angle e.g when youc have a gun selected press up + right to go in the middle of them if you could do that you could have defence on the left and right not just up and add towers e.g another gadget could be tower component where you placed it on the level on a screen and chose one of the weapons to put on it
i finanly completed lvl 6 after 12 deaths any one want to try my challenge?
press +if you wanna try my challenge witch is compelte game within 30 deaths
in my last comment i complained about not enough penguins well THERES NOT ENOUGH TOWERS
add two new towers
1.missile tower shoot deadly missiles very quikly
2.iron tower this tower is as strong as the basic tower but has a iron suit on so it cant be destoryed
you should add... get extra lives +1 witch you can do when you level up plus their should be a few more penguin types i got a idea for some
1.sniper penguin they can shoot towers and stop them from working for 3 seconds
2.split penguins when you kill this guy he splits into two and it goes on untill there is 4 of them
3.invisble penguins that can only be detcted with certian towers e.g bomb tower
