Interesting game, but the player movement was very off, you slide on the platforms like walking on ice. The enemy shots would often pass through walls, and damage me, and the level design was pretty confusing, there were a stage where I had to look everywhere to find the exit. Excluding those issues, the game was very easy, and the bullets bouncing off walls helped a lot, if this wasn't intended, it would be a nice addition to the game, along with more levels, enemies and upgrades.
