One of the best ideas I've seen this jam. If I were simply tallying the points I gave, this would get the most. Now I'm not sure how qualified I am to rate this, since I haven't actually beaten the game myself (severe skill issue on my part), but I have seen others do it.
The artwork is almost perfect as far as i'm concerned, aside from some clipping of the conveyors and a bug on my end where there is no explosion on death, which is strange because I have seen it before, or at least I think I remember there being one? Oh and the controls being shown in UI elements would have been nice.
Audio is definitely one of the best this jam. The music fits perfectly and is even partially in sync with some of the hazards, which also have their own sounds. Personally, I would have liked to see a sound to indicate the speed boost being active, maybe even a mechanical whirring perchance? (totally not me just wanting one of my favourite sounds in every game that has the opportunity).
For the narrative: I've heard an interesting theory of this possibly being a prequel to a prior semester project Post-Haste, which would be hilarious, but there isn't a whole lot to go off here. You're a bomb in a package that should not be damaged.
Now for the enjoyment, despite me never having beaten the game myself, I see potential. There is just one main complaint I have, which is the reason I gave up: the speed boost feels inconsistent. Sometimes it keeps up until you let go of the shift key, sometimes it lasts only for a moment which is very frustrating when all of the jumps in this game rely on it. Oh, and again, the controls on the UI would have been nice. Speaking off, why are all 3 volume sliders in the settings menu labeled music?
That concludes my review. Thank you for your participation and great work on your "totally not a rage game".
