Upgrade Superfluid & Marketplace Demo

This [environment](https://assetstore.unity.com/packages/3d/environments/landscapes/polygon-tropical-jungle-nature-biomes-low-poly-3d-art-by-synty-234253) and [these](https://assetstore.unity.com/packages/3d/characters/snail-virus-bacteria-or-aliens-137957) to play.
Game logic:
snail can be tapped (or spam spacebar) -> will change animation
snail can be moved around on the island environment
snail comes with different speeds (0-5) -> important, since moing on the island is important to get to the places where
other snails huddle (for flowrate multiplier)
an event takes place (just simple things like partice systems spawn so to indicate where high flowrates might be hidden)
snail will yield for some time with degrading flowrate if player does not come back to tap it
Done!
NFTs will be those different tiered snails )I change colors a bit to make sure people understand they are different)
Strech goal:
Really slow snails can “invest” token they yielded to buy speed boosters (so player has some kind of control over this game)
