CraftMine is a nice little online game that you can try out. It offers 2D Minecraft graphics. Your objective will be to control a hero that can jump around and mine many different materials. The materials can then be used to craft items that can help you survive in the world. Aside from that, there will be wildlife awaiting you that can easily kill you. It’s better to be careful then and to sometimes run away. Don’t forget to eat and drink. Also, stay warm during the night. Good luck!
