I was a scripter for most of Pysis and contributed to the design of the game. Although I did not script the boss fight, that's all Pete.

Examples of things I scripted include the crafting system, the spear attack and slingshot attack, and collecting items and storing them in your inventory. I remember during the development of Pysis, originally only Carlos, the brother you control, would be seen in parts of the game where the player was controlling. Ethan asked if it would be possible to include Freddy in the scene as well. Adding Freddy turned out to be simpler than I thought. I duplicated and edited the player script so that Freddy would move towards Carlos and play the corresponding animations depending on where he was relative to Carlos.
