Very fun addition, and definitely more difficult. The slow falling did not work for me, and despite having some trouble, I was able to make it past the slow falling section and beat the game without it. (Is pressing T supposed to warp you to the credits?)
Interesting update, especially with the removal of block, special, and the Grasshopper character, but Housefly parrying really makes the combat more interesting. I was still able to create two new skips to be used in the speedrun, and the last one WILL be found.
Only issue with the run is not being able to kill the ending larva (yet), but besides that it is completely pacifist. I'd be willing to send a run through Discord.
