Super cool game - digging was satisfying, and collecting resources and upgrading was, so not much to complain about.

Being able to dig up would have been nice, though I understand that might be part of the "strategy" of the game.
Also a super minor thing is I felt like once you start digging it should lock in that direction until you're done so you can release or change the arrow keys.

I liked that unlike many low resolution games you managed to fully communicate which upgrade does what. The jetpack mechanic is also a very good idea. Very good package, overall.

my time \o/ 

I panicked when I realised I'd cut myself off from some ores because you can't drill while flying ^^ I sacrificed maxing oxygen just in case haha. Great game, really fun to play! :)

That was lovely :) A meditative experience underlined by the chill music. Loved the sprinkle of micro-strategy required to get around the fact you can't drill above yourself. All around elegant design, well done!!

Really nice game :) I loved the graphics, music/sounds and the resource management part. The jetpack was so useful, I really wanted to keep exploring the caves.

Great game!

I repaired my ship but didn't want to leave empty handed, then almost ran out of O2 in my maze of tunnels filling up my inventory. But I loved the game! All the mechanics felt great, and I think having the unlimited jetpack really helped maintain the flow of the game. Also appreciated the design acknowledging how terrible an idea mining upwards is, lol. And the moody chiptune soundtrack was perfect for the experience. I played with a controller and everything was very slick. Great work!

Lovely fun Pico-8 game. I really liked the music and graphics, it gave the game a really moody atmosphere, definitely felt like you were stranded on a planet. A very nice combination of simple, familiar game mechanics that come together to make a fun experience. It plays really well on a smartphone with the built-in Pico-8 touch controls.

Really chill, nice visuals and music, a cool game to feel the vibe and dig away. It has clear objectives and it's very satisfying to gather the resources. This game jam is really making me consider trying making something in pico8 :)

I also think not digging up is super ok, it adds strategy in this scenario. One thing to consider is that I never felt I was in any danger. While this may be intended, and it contributed to the chill aspect of the game, it kinda made me feel that the o2 tank upgrades were just to stay a little longer down there and not for safety.

Overall great experience, good job!
