Thanks for the fantastic review Paragon, it was fun reading it!
The red 'shroom is a placeholder, I made it quickly just to change it from the default. The original jukebox was based off of the jukeboxes you would find in the 60's, and at the time it looked hilarious, so I kept it. I'll change it up a bit in the next update, and make the rainbow one an alternate.
The ores are actually subject to a major overhaul, and so is the crafting bench. The chests are going to updated too, as well as the flowers. I'm going to change the lava in the near future, but likely not in the next update. I'm going to update the water too: I can't say if it will be in the next update or not though, I'm not sure currently.
