This kind of game is totally up my street! I love that feeling of being a scrappy lil guy jumping and scrambling all over their ungainly mech home to explore and find a way out! I really like the choice of using wheels for all interactions, and I especially like sending the mech turning before engaging the throttle and vice-versa. Those kind of simultaneous interactions should definitely be explored post-jam! You really captured the look of a brighter version of Mech Warrior 2, in terms of presentation literally all it needs are interaction highlights and sound/music.
In terms of issues, I think the player needs a bit more air control or the platform around the mech should be a bit wider, even when being careful it's too easy to fall off. I also think it would be worth having wheels interactable in the bottom half of the screen or even just by distance so that steering and throttle could be engaged a bit more smoothly. A neat addition would be to have side and rear windows/mirrors to further sell the feeling of operating heavy machinery.
Given that everything works through wheels, it surprised me initially that you couldn't place them where you liked. Obviously this complicates the design, and you might want to add constraints (e.g. once placed a wheel can't be moved), but I think this element would suit a metroidvania and the fantasy of operating this machine. If you wanted to look for inspiration for more mech components I'd suggest looking at heavy machinery used in construction.
So to reiterate, I loved this! I'll be patiently awaiting the full thing!
