I get that it's a game jam, but the core mechanics arent that interesting or even particularly fun. Also, the visuals/presentation is hella boring. The design of it isn't really evocative of that theme "small planet". Even with crude graphics and bad audio, the fundamental design of a game's mechanics can really carry a game. Usually when I do gamejams, I know that all aspects of my game is gonna be constrained, so it acts as a good exercise in design. "How can you make the most out of what you have?". Jams are always a good way of developing that. Hope this helps!
