itwas really boring, you sholud be able to upgrade things like how bouncy the tank is... eh.
Overall well done, but...
Even when you have full or near-full upgrades there are times when you can go a good 5-10 seconds with absolutely nothing spawning. Pretty infuriating when you're really close to leveling up and wind up running out of time and have to start over because of it. A save option would be really nice as well. However, other than that it's a good game.
for the first 5 minutes
i beat it with 30 and im still alive :D
Entertaining for a while
This game is very entertaining for the most part. It does get boring after you play a while.
