some of the levels feel a bit like wallpaper.
not all the levels, probably not even most of the levels, but certainly some of the levels, especially in the new groddle.
platform place is a good example of a level that feels like wallpaper. it is difficult to gauge the width and exact location of the "platform" branches. even after i've sussed out the invisible platforms that seem superimposed on the wallpaper, the whole level still feels a bit flat. there are other levels with similar problems when a "path" diverges uphill and straight across a seeming thin ledge which is actually a drop.
maybe most platform games are too obvious about what are platforms and what aren't, and glitch is going for something more subtle, but it is frustrating to miss jumps and not know why. it can take a player out of the game when some "background" elements you can stand on and others let you fall.
