Oh, I didn't notice. Because of this website you often download from the gamejam site and dont even see the descriptions section. Although I figured that you had to collect those "PC's" it was still way too difficult. Yes, I played on Medium and as you said you shouldn't choose because it may be too difficult, ingame it wasn't very it would be that difficult. It would have been probably better if you reduced the map size by half for every difficulty or at least make the maze more orientable, since you never really knew where you are or have been to it can be quite difficult to find the last collectible.
But as I read that it's all procedually generated, good job on that, that's quite impressive for that short time period. I think it was an overall okayish experience, although as already mentioned it may too hard because you lose orientation so fast.
