Oh yes, and if there is no oxygen, how is my character still alive? How can even mutant monsters live? Take out that bit about how no oxygen remained on earth.
Balloon in a Wasteland meets City of Ember! Its great, but I would suggest making some tweaks. (1) Make the city burn in the background. (2) Your character should be wearing a radiation suit. (3) Allow you to buy defenses, like barbed wire. (4) Add some more futuristic weapons. After all, this is the future! (5) Make the plot more in depth. Add why the war started, and who your character is. (6) Name and show information about the monsters. Every time a different monster is introduced into a new wave, tell the player what it is called and its strengths and weaknesses. Hope these suggestions help :)
Holy crap! Its Drift Runners...in 3D! I love it, LongAnimals, but the drifting seems to be a bit off...or at least very hard to control. I think some adjusting needs to be made :D
You need to add more maps, upgrades, a proper tutorial, a storyline, and then this game shall be awesome! I already love it, but you should add these things.
Level 14 seems hard at first, but its actually not that hard. I would recommend having the Commando and leveling it up to level 29. Then buy a mini gun, equip ammo feed and bouncing betty. Then, the level should be quite easy.

It's not meant to be easy, but it is worth persevering, I think. :)
