I liked the graphics and the overall feel of the game, and the exploration vs fuel management is fun, if a bit unforgiving. There were some features I couldn't figure out how to use, such as repair, and I never was able to find the first set of resources. I'd also suggest making mining more automatic- having to click and hold on every individual block is a recipe for carpal tunnel O.o
Looks like a game with a lot of promise. Interested in seeing what this would look like with clearer instructions and a bit of polish.
