Thanks! I'm glad you like it!
Regarding the executable: In Godot's export dialog there is an option "Embed Pck". Make sure it's checked :)
The "^ Predator" entry in the list is actually not a guy... It's just a default entry marking the point where the scores get "pretty good". However, you're doing great! You really need to explore the map to find the best hunting grounds and powerups. You wont get above 2000 by only chasing sheeps, that's for sure :)
Thanks for playing!
