Roger Li:
The character sprites, animation, and special effects are beautiful and extremely well made. The game mechanics (power ups, unlimited waves) are also very interesting and easy to understand. The UI design is also quite thought-out and I really like the two-joystick design. However, I think the game gets a bit overwhelming after waves and waves of enemies. I think it would be better if there's more breathing room, such as periods of low enemy spawn rate followed by hordes. I think it would also be interesting if there are more elements/variables considered when it comes to level design, such as adding obstacles/platforms or borders rather than letting the player roam in a limitless level with essentially nothing other than enemies and items in it.
