Thanks for the detailed feedback! Really appreciate you giving your time. I agree we are lacking in the polish dept. Our reference for the assembly phase was a minimal version of the "customisation menu from Armored Core 6 " so we definitely overscoped and didn't have time for the tutorial (which we had planned initially).
In terms of difficulty we wanted to have the player get accustomed to the movement in the early levels but I think it gets difficult after lvl7 and the parts you get after a level is random so that also adds to the difficulty if you don't get the correct build.
Also we didn't really get time to playtest as much so we just fixed the game crashing bugs (in the initial levels at least). With better planning we might have been able to add some qol stuff but no point in thinking of that now😅
The planet rotation to indicate movement seems like a good idea though. We will try to add it if we decide to work on this in the future.
