Hey thanks for writing this out and expecting so much from the game. I think these are valid critiques of the level design, controls, and mechanics. About halfway through I decided the game didn't look pretty enough and I spent a bunch of time tweaking the art. As a result of this and other decisions, level design was kind of crammed in at the end and I think the mechanics suffered and I fell back on established platformer tropes which did a disservice to the underlying ideas.
While I'm not sure if there was a chance of EW reaching its full potential in just 48 hours, that doesn't invalidate your critiques and if I end up going forward with this game I will take this post to heart.
