This is yet another that I'd call a contender for this year. You could, I say without exaggerating, probably take these mechanics and ideas and polish them into a commercial release if you wanted.
Good:
- Pure fun factor is already pretty decent once you get the first upgrade and start learning to use it
- Fun factor shoots up exponentially once you get the glide
Bad:
- I may have sequence broken a bit more easily than intended and am pretty sure I got to a point where I more or less died to escape a room. (But I kept the item which was nice, and it might have been theoretically possible to escape)
