Hi @iamcreasy. Thanks for the feedback.
So basically this game was done for a Mini Ludum Dare # 59 which is a gaming compo.
The idea of this mini ludum dare was to create a game using a given sprite sheet and then creating a sprite sheet using the sprite sheet template provided.
Then at the end of the compo each entrant will swap or use a different sprite sheets of someone else’s game.
So there were many strange sprite sheets submitted. That is the reason for that one you saw with the glitch.
Go to the options menu and turn off the random sprite sheet option. This will give you only those ones in the assets.jar file.
