Yeah, I don't know how you got this one out in a week, and with a level editor too, but this is insanely well done. I have very little to say that others haven't said already or is super nitpicky- that torque feels redundant when RPM is always an exact target, the UI is beautiful but the text is a bit small in some places, the gears should snap in the middle instead of the top left corner, the tutorial text for each stage disappears too fast, blah blah blah.
This is the first time in any game jam where I've played a game and thought "Yeah, I would buy this if it was a full release". Second 5/5 in all categories I've given out this jam, well done!
