As a fellow wagie, I relate to this game.
The game played well. I like the Pepsiman inspiration.
Right now, I think you could add a raking at the end of the levels, based on time you took to complete, coke/cofee collected, times you got hit...
Also, at the end of the level when it is counting the collectables, it would be nice an option to skip the counting.
Those are my two cents so far!
