levelhead looks really cool - it's a 2d platformer game about making your own levels and sharing them with other players:

(seizure warning for the video - there are a bunch of quick cuts)
unfortunately, it's quite expensive...

These new elements were tolerable in isolation, but it got to a point where (for me, with my slow reaction times) whether I beat a level was more based on random chance than anything else. The new enemies and obstacles became frustrations, rather than challenges.
And this was just in the official campaign, I haven't even played any user-made levels.
Overall, I had fun, but not enough to want to keep playing against these frustrating late-game things.
