Yes, actually most of the errors are intentional, to give that feeling that the game or the 'system' is failing.
An example of this is the sprite flickering, the pause menu stopping working after Game Over, negative scores and negative infinite lives.
I plan to release 2 versions of the game, one version without the errors and another one that includes the errors to fit the theme of the game jam.
Thank you very much for playing! I really appreciate it.
