The genres match really well, which would usually be compliment, but I guess for this jam it's a criticism :P Could've used some music for sure. I make music so if you're ever in a crunch and need some, feel free to reach out. I read you didn't make the graphics but I still really like the combination you chose, it fits together well.
I really like this-- I'm a sucker for platformers with good controls, and love mining/gathering in games. So good combo for me. Good job!
