Made for Ludum Dare 45.
Update 2019-10-09: Fixed rendering on Windows and Linux. Minor visual and gameplay polish. You can still play the compo version at LDJam website — Here.
P.S. We thought, the soundtrack (or the jist of it) should live on, so it had been re-made into the album version in early 2020. It's called 'Oceanic' on the record. You can find the album Colorspacious by Polygrim (one of us who does audio).
