Subway Miner was a nice submission for the Game Jam, very polished and amazing that you could make a runner game in Minetest. Good Job.
But I feel like it was kind of missing something, maybe some scenery? Better textures, louder mese sounds? I didn't feel like the music fitted very well. A new slide animation? New and more random level gen? I didn't even know how to slide right away, maybe just add some hints at the biginning?
Anyways, good job!
