On Planet 1-10 The last shutter doesn't open even after getting the pod.

Wow, I was not expecting to see someone with (if at all) inspiration from Sega Genesis Sub-Terrania game. I'll have to see bout giving this a try!

The sound effects drown out the seemingly Amiga-inspired music that I quite enjoy, it's a shame. It would be nice if we could have an option to adjust the level of the music and SFX independently. Right now the ship thrust sound is way too loud.
