yo!! i love quake styled shooters.... this was a nice surprise
i liked the physics, i think they could be better with some tweaks. they can feel a bit slippery during platforming segments, and some view bobbing would've gone a long way i feel. still, the fast paced gameplay made this quite fun to play through and i have zero complaints about the aiming controls :)
i noticed after playing that the jam page had a tutorial image on it, perhaps that would've been better to put in-game? or, at least on the game page itself. i think in general, the game would've made more sense with some visual tweaks. instead of a blue square, perhaps a literal "garbage collector" would've worked well? and instead of color changing to suggest a memory leak, perhaps the textures progressively lose res/color depth, and/or the music gets progressively more crunched.
gonna give a special shoutout to the music here, the atmosphere of it is really good, i think it really elevates the game. i think it was a good choice to emphasize the more ambient angle like the original quake did, it works well.
i didn't figure out you could rocket jump until the last level, so i ended up playing through the entire game again just to try and optimize my movement, which is a pretty high compliment for a jam game! ^^ it's quite a good start, i hope you keep making games!
