A solid entry into the jam. Once I understood the red vending machine was 1 hit, the yellow was two shot it kind of became too easy. Each enemy type was easy to avoid at distance with its attack not even triggering. I didn't feel the upgrades had a great impact on my ability to kill the enemy. I got to wave 12 - with 14 lives. I pretty much became untouchable. Overall a good attempt, more development would see it improve.
