This one is interesting, is a very simple game, but it doesn't control very well with the difficulty that is given to the player (requires precise movement but can't move diagonally), and the collision sometimes play against the player. There are moments where moving towards a wall push the player to one of it's sides, putting the player right in the direction of an enemy. I was able to reach stage 3 but stopped as soon as i saw that enemy that shoots the wavy pattern balls. Besides that it does feel like an early NES game, and the music is really good.
