Hey! Here's my thoughts:
Gameplay
For some reason, the game occasionally did fps-bungee-jumps for me which made it hard to reach a score above 300, which is sad because while the game ran smooth, I really liked it! I would've loved to spend even more time with it and be able to do a few upgrades and such. Perhaps it was mac proving yet again what poor choice it is for playing games - but I'll make another attempt on my windows later! ^^ I like that you implemented more than just simple arrows, with pickups and such, that adds a lot to the replay ability and keeps the game interesting - when you always have a chance of regaining after loosing.
Theme
It absolutely follows the theme!
Aesthetics
The look of this is very nice! Part of the UI feels very "standard" but the level itself looks really good and felt like some thought was put into it. The arrow-filled ground is such a cool detail that adds a lot!
Sound
Very well made/chosen/placed sound effects, but the music was not quite as good and became a bit of a stressful element.
Overall, a fun game and I hope more people'll play it! I know I'm going to give it another shot in a few hours when I have access to windows. :D
