nice short but sweet game. Was able to repair the balloon in 5 minutes with just buying guns and repairing(and repairing upgrade) and of course taking some 2-3 quick naps when the stamina got low.
I have some suggestions though, to make the game longer or more difficult ang interesting.
*Make the creeps spawn in every direction instead of just one. This will make it harder than just spamming bullets at the spawn spot. Put the balloon and fort at the center.
*Shorten the stamina to 1/4 or 1/2. I think it's too long.
The MGs are quite powerful, but I think that's why i liked the game. Pls don't nerf it.
Anyways it's a good game but really short and doesn't entice me to play it again real soon.
