Nice work! I finished the game and loved the dialogue and story building.
I had some trouble with the physics lol. Got launched a few times but one time it was to my benefit! Was a good idea to implement a way to get unstuck. The platforming was hard at times, sometimes the way the character reacted to falling when a platform goes down would get me killed. I did follow your request and pressed F6 upon entering level 3. Not sure if it was supposed to happen, but I carried the friend at the end along for the ride.
Overall, this was an enjoyable and great looking game, it just needs some polish on the physics and controls to make it less punishing for reasons out of the player's control.
