Hey! :D I see you are a man of culture as well, my main areas of interest are platformers 2D and 2D related solutions. Im a programmer but i dont have nearly as much experience (i code and do stuff around games for like 1.5years 24/7 at this point) I also like strategy and the most citybuilding, althrough the best strategy game i ever found was actually working around games, as there is actually some level of depth and true complexity.
As for design its very hard to judge as its always heavily mixed with preference, I for example couldnt handle the repetition in Kingdom 2 crowns and after 1st hour that was amazing i started getting bored to death and quit (same for ratropolis), northgard was better but after few takes i felt like solving some 5 dimensional equation and making random moves intead of just enjoying the game and also progression was too tightly capped at the endgame. As for my preference in platformers 2D (i chose them as i could release them even on my own) i would say exploration and arcading are my favourite with focus on action.
The problems of design your proposing are very simple as limitations it imposes. Everything has to happen on one dimensional line so there isnt really many ways that those things can happen. With games progression shifting variety of tasks and games mechanics could be the most important element of design.
