@ahintoflime and @taldius thanks for your input. I agree that the controls are very rough and missing general indications.
@roberto-romao thanks for your suggestion, it's really missing a speed indicator.
@awerar we didn't had the time to finish our mechanics, so the ore patches on the slope ended up redundant. The initial idea was to have some sort of a cooldown, and you would had to pick the ores on the hill, but we couldn't figure out a good way to do it in time. In the end we liked the concept of the slopes, so we put it there just for the kicks.
