Cool base idea for the game, same for the bonus you choose at end of level, which comes with a malus. But it would need some more time to make it cool. I guess not enough time to implement a lot of things (I was disappointed the giant dangerous barrels didn't explode when shot :p, but also no health, no timer, collision issues, etc...). Navigation was a bit painful too (I'm not a big fan of this kind of controls, and player can often be a little bit blocked by collision from environment.
Fun intro :)
