A game that I made it costs 25 robux.Still in Pre-Alpha.Read The game's Description for more details.Link: https://www.roblox.com/games/17894034...
Note:I have finished this tycoon so there are actually 3 emerald upgrades 1 for door and shield(most recommended so you can go to the moon) second sword giver and third is a mystery(only exists on the moon tycoon) The game saves even emerald upgrades,emeralds and Power.I will do an auto save soon so when you disconnect you won't loose your data.So keep on mind disconnecting can make you loose your latest power/emerald gained.
