This is probably the most polished game I've played on the jam so far! The visuals, the animations, the gameplay and the upgrade system were awesome!
The gameplay gave me some Terraria vibes, and the music (a banger) was reminding me somehow of Jetpack Joyride.
I will give you some feedback on the game though, because there are a few things I would have designed differently.
in level 2-3, you get a massive spike in power, that make those levels kind of a breeze. You can go around the level and pretty much mine everything. The only limiting factor are the enemies, but since your power spiked, they are not much of a threat anymore in their numbers. I really like the design and animation of the enemy characters, but they don't pose a threat enough. They can only hit you with their ranged attacks and you can walk through them without taking damage (?).
I know this is a game jam with limited time frame, but in a full game, I would expect 2-3 types of enemies, that could have added flavor and diversity to the gameplay.
One way to balance the difficulty and prevent farming would be a timer, which I think would fit really well into those 3 first levels.
The green ore is a bit frustrating, because sometimes there are no generation for it in a level. I think having at least guaranteed ore vein for the green ore per level would be optimal.
I think the 'no energy' overlay is good to indicate that I run out of energy, but some sound feedback added on top would be top notch.
Potential bug : it is possible to get stuck in the level with no possibility of coming back to the ship. That would involve mining everything down to the bedrock, but its still worth taking note of (the jetpack fuel may not be enough to reach the ship)
The final boss was cool, but since the enemies spawn is set on the surface, mining downwards make them take forever to get to you. maybe moving the spawns vertically to follow the player would be a nice idea.
To end on a good note, Ill point out I really liked the aesthetic of the tutorial, and the UI is very slick. This game was incredible! Good job on submitting for the game jam!
