I love all the different modes! They all feel super useful! Only issue was that the monkey mode seemed to be a little inconsistent. Sometimes it'd let me climb up and over the wall, and other times it wouldn't. Either way, fantastic job!
I had lot of fun writing (and rewriting, and rewriting again) the hitbox and collision detection code, thought I'd managed to iron out all the kinks but not too surprised to hear I missed a few. Glad you managed to enjoy it all the same :)
