The biggest thing to note that I haven't seen any other comments say yet, is that before you hit the 'confirm' button, the window with the instructions obscures a lot of the level, and there's no way, according to my understanding, to close the window before hitting confirm. Most of the levels I played it wasn't a huge deal, and the window is slightly translucent, but it's definitely hard to plan ahead without knowing the full details of the level. And considering that you only get one shot at the level, since there is no retry button, it's very important to know exactly what's ahead. Cool mechanic, and nice entry!
