Sylenius Mysterium

This game by a good author (see 'Delusions') reminds me a bit of Gris et Jaune by Jason Devlin, another talented author. Both games have very strong openings that hint at a great game full of polish.

However, both were not completely finished/polished in time for the competitions they were entered in. This game, in particular, falls flat in the most exciting part: the actual game simulation. You play as Mario, and you have to jump with timed Glulx effects, but it just doesn't work out, and later levels are, I believe, unfinished.
