hey there, thanks for playing! I'm glad you like it but sorry to hear there are some issues ~___~
> you don't actually have to use any of the items; the game will allow you to progress naturally as you get them.
> sometimes rpg maker 2k fonts come out looking completely different on people's machines -- not sure why this is but it's a known system issue, you can download a font patch here that should fix it: http://www.indiedb.com/games/the-sewers/downloads/...
hope this helps! please feel free to comment again if you have any more questions <3
