I'm reminded a fair bit of Downwell - I assume you ran out of time to implement the shop? There's the basis of a fun game here, but as it stands, it needs a reason to delve deeper into the planet, even if it's just "just a high score".

Thanks for your feedback! Yep, I didn’t have time to open a store. I miscalculated the possibilities and timing. Ideally, there should have been a store and procedural world generation. And if it’s absolutely ideal, then boss fights.
And about Downwell, yes, when I thought about descending into the void, this game came to mind and I wanted to get a little closer to its style.
