This is an interesting concept. It is a lot of fun to play and the pixel art is really well done.
Right now all ores are the same. If you continue working on this, you could make it a little more strategic, like giving the ores different properties, rearranging minecarts etc.. I think this game can be expanded in a lot of interesting directions! Good job!
I’d like to know what properties for ores you have in mind. :-) Different ores were introduced to enrich the gameplay by making player mine them selectively. So, you can’t just spam mine everything (except for the first level), you have to stop your cart and align it with the desired ore.
And thanks for the kind words, I’m glad that you liked my game!
I thought along the lines of having a score system. So maybe some ores fill up a cart faster but are less valuable? Maybe some have to be put into a special cart? Maybe some enemies steal certain ores? But that's only in case you wanted to add mechanics to the game, right now everything makes sense as it is.
