Somebody picked me up, yay!
It was a good concept with responsive controls and a decent presentation considering the time constraints. One of the first thing I noticed was that the explisions from the rocket launcher felt really nice and had a kick to them!
At first, I wasn't sure how the game was out of control, but then the timer completed the first cycle, and I was like... oh :D It was a bit difficult to figure out what exactly changed each time, and what were the rules for the changes. And I never figured out what the mushroom was for or how to activate it. It would have been good to show the player how long they're supposed to hold out, or even that the game has an end, as throughout it I wasn't sure if there was any progression in it at all. So in general, I feel like the game could communicate more to the player.
Thankfully the health bar was generous enough to let me figure some of it out and hold out long enough. Great job!
