The game Plasma Dog is a 2D-Platformer that is running on the Omisego blockchain. It's a 2D-Platformer where you are a dog that jumps on top of enemies to destroy them. Along the way you collect Blockchain transactions. The art style is a cool modern neo-colored pixelated future.
I enjoyed playing this game, and I was really happy that I gave it a chance. Many other games that have been released on top of blockchains haven't been very good. The game is browser based and a lot of fun.
