Congratulations for this first game jam game.
It's pretty addictive to play. The controls are unusual for an arcade player like me, but once you get used to them, it's OK. More feedback would be welcome, such as how many time you have survived so far, a flashing bar or something like that when you're close to death. It can make you change your strategy to survive a few seconds more. Finally, an improved level design can make the challenge grow crescendo. I enjoyed playing it! Nice job!
