Added things that improved the visual quality of the game, (if you like to say so) such as:

Backgrounds, signs, wooden crates, new enemy (boss2) and new spawn point to enemies to spawn from, that works after 9 minutes has past.

i think that was all of it. Next update will probably be something to do with sounds, but we'll see. (Or maybe it can be a whole new secret mode to unlock 👀)
