This game is cool. It and Nine Lives Too Many are similar in the goal being to kill a pet. I didn't explore it myself, but I can tell there's seriously a lot of potential for speedrun like you intended between standing and running on all fours. I felt as though the colliders were a bit weird and required you to switch stance in weird positions (in the pipe thingies mostly), but its understandable, I can see switching stance being somewhat jank to make. Great job, you should be proud!
