Core Mechanic: l had a lot of fun playing with this one. The levels had a gradual ramp-up in complexity and precision. The times when the little guy went off-screen were a bit stressful, but I handled it fine. My main issue is that the red guys were mostly inconsequential - there were only 2 levels where their presence genuinely concerned me. I also liked the coins as an extra mini-challenge in each level.
Game Feel: Move with the arrow keys felt awkward, but using the mouse felt much better. The various sounds made it obvious what each of my actions were doing in the heat of the moment.
Visuals: The colors are pretty, and the characters are easily readable 👍
Sound: I like the little pew-pews of the gun
Theme: The connection between the game and the theme seems pretty weak. I guess the fast, slippery movements of the gun could count, or maybe spawning the sun in the sky as a result of picking up a coin
