The game is quite tough. Being confined to a small space to dodge makes the game quite challenging, and can be frustrating when you don't realize your at the edge of the circle. The gameplay and technique is fun, though. Sudden movement to the limited space is also very frustrating. There are an ample amount of enemies and enemy types that bring a lot of variety to the game, though. The visuals are also made really well, emulating a kind of old-style game look. Great work!
