Terrific glance and quite awesome development, I see you place a whole lot of specifics and touches through the time body, as other outlined, neither looks lousy at all! In truth I really encourage you to use the cool track record the deeper you development in the run or match if is countless runner, or if its mission, amount etcetera, you can probably use the suitable facet track record for deeper amounts. I would go and say if its feasible ( not sure what engine you working with, seems like Unity? Perhabs tweaking the coloration strategies for other amounts or as you development through the match, to give it a awesome alter of scenery with no much additional do the job, aka alter coloration pallete through development or amounts, ex: the sky is orange then floor is environmentally friendly etcetera etcetera.
Other than that, this kind of video games have to have a awesome musical concept, I am curious to see what you have finished or would/will do in the seem and soundFX division. Techno? Melodic? It is vital to have probably a loop new music that does not come to feel like a loop, if it makes sense, or atleast clean up seem results that blend with gameplay. Idk I guess I treatment about track record new music or Forex additional than I really should haha
