Really nice game!
Sorry this time I couldn't make time to join, so I can't rate your game in LD.
I think the introduction could be improved, it took me quite a while to understand how it works. Especially the devour mechanic, since there's no indication of how "fat" you've become.
There was also some bug with the devour, when you hold the down key and you get stuck in an infinite devour state. Also, in my "clear" run, the doom wall kind of got stuck at -99m (was it a bug?). In other runs, the doom wall always progress regardless of how "fast" the wagon run. There was no indication of "speed" change when the number of pullers change.
I think it would be best to see your wagon dynamically outrun the impending doom wall briefly when you have a lot of pulling force (like when you have 6 pulling abominations), and only barely keep pace when you have 4 or 5.
