This was an Ectocomp 2016 speed game. This is set in a MLP-type world, similar to Owlor's other games.
You are a hardened and vicious magic-using pony out for revenge. You need to go an a quest to find the ingredients for your potion.
This was relatively straightforward, and fun, with good cluing, until I got stuck on one ingredient for a long time due to misunderstanding a description.
It is unpolished and didn't draw me in, but that is due to it being a speed-IF.
