Well it's a 2D platformer, you jump on platforms. Sometimes to other platforms. Sometimes you jump up to platforms, sometimes you jump down to platforms. Spikes are sharp and hurt you, as do saws so avoid them. The narrative is pretty simple as explained at the very start, stars have fallen and you need to find them. Using these platformer abilities you can explore levels to find them.
No apology necessary, I'll make it more simple next time.
FEZ was a huge inspiration, but the FEZ backgrounds are quite different, typically blues of floating islands, my background was green and bushy. I wanted to capture the 'fresh air' feel FEZ had, thats all :)
(This might come across sarcastic but it isn't, I'm quite distressed at how this game wasn't 'understandable'?)
