What a glow up. Seriously, we're talking Metroid to Super Metroid level here. Taking a simple concept and so thoroughly expanding it that the prequel seems generations behind.

I think there is something important to learn from SteamWorld Dig's idea of player generated level design. Now, I'm definitely not the right person for the job (I'm writing this at 2:30am help me) but I'm sure that someone smarter than me would be able to mine those depths.

I like the funny robot digging games.
