Sorry for the late feedback report, but some things that I found difficult were the platforming. I was OK with the MegaMan style gameplay, but when the platforming came in, I had trouble with distinguishing what was a pit and what was not a pit. I also found Gems hard to acquire and it took me a while to figure out how to jump from ladder to ladder. I stopped playing at 1-3. Also, is it just me or the save is not working?
On the good side, I liked the weapon system and the slide, despite not using it much. I also liked all the little interactions with the shopkeeper about skiing in the mountains, and all the optional puzzles.
Out of 10, I find this is a 7.5/10.
