So the jam and it's rating is over now. It was a good experience!

I have created the first update for the game with following changes:

• Massive performance optimization
• Game runs now on solid 60 frames
• Chunk system added for dynamic map loading
• Display amount of items in inventory available when crafting
• Decreased amount items needed for crafting
• FPS counter added (F9 show/hide)
• Custom mouse cursor added
• Bugfix: flickering lines between tiles fixed

Have fun!
