Did all the intro levels last night, then spent about 20 minutes trying out various custom levels.
The game is great. I wasn't expecting it not to be, as I loved N+ to bits. The DS4 is a wonderful controller for this, but I did find it way more comfortable to swap the jump to Square instead of X. Shame the game itself doesn't have button config option, rather than having to use the PS4 accessibility options. I was also finding I was having more success when using the d-pad instead of the analog stick.
Only negative is that I wish you could retry the last level again from the episode menu. Too many times I completed a level without getting all the gold, so wanted to retry and get them all, but pressed X to continue rather than Triangle to retry.
