I beta-tested the French version of this game, and played the English version during IFComp and now.
This is a funny game in a very particular genre: the 'gain powers by eating' genre. Other games in this genre include portions of Spore and the Adrift game Mangiasaur.
Using Vorple, En Garde replaces the parser command line with colored buttons. These buttons are, at first, unlabeled. This represents your mental state. You begin this game as a weak, unintelligent creature, but quickly become more intelligent and powerful, and your options change accordingly.
This game is short and not too complex, puzzle- and story-wise. However, it's value is boosted by its amusing dialog between various species and people., which elevates it from a 4 star game to a 5 star game for me.
