A cool game. I found the levels quite fun, interesting, and with a decent amount of variety. The game is quite simplistic in its design, but still does its job at being enjoyable.
What I liked:
1. Solid controls
2. Nice Background music
3. Cool voice acting at certain events (e.g. when you beat the game)
4. The theme is quite consistent throughout
What I didn't like:
1. I wish the aim cursor was a different color other than yellow. I can barely see it sometimes. I suggest switching it to either red or green
2. I didn't understand what the other power ups were doing. I noticed that the black and red ones are bad, and the rest were good, but that's about it. Some explanation would be helpful
Overall, nicely done with this project
