Fun 2D mining game.
Even if a bit on the hard side, i really enjoyed racing agains the cold to try and dig coal as quickly as possible. The fact that the mechs slows down as it gets colder is also a nice detail but makes it quite a challenge to balance your time mining and planing your return trip to the furnace XD
My main gripe is that while digging downwards, you don’t seem to drill more than one block at a time instead of 2 if you’re in between 2 tiles, having it be like this would make the dig mechanics a bit better i.m.o, especially considering they seem to work this way already when digging horizontally.
Another small issue i found is that you didn’t seem to have walled off your level so if you’re not carefull you can walk and fall off the map.
Other than these it’s still a nice entry, and i liked the challenge, even if i died quite a few times thinking i’d have enough time to go back but forgot to take into account that you move slower and slower as you freeze haha :p
Good job to you guys :)
