0.1.c & 0.1.d - polishing further!

I've quietly shipped two minor updates, here's a combined changelog (lol as if I remember which version fixed which ones)

• A scanning glitch on screen transition removed (again..!)
• Ahavena breathes bubbles now.
• Variant forms of some Emuuroms now show up under the same entry, as they should.
• A flipped swimming sprite for the player! It now conveys better that you jump downwards underwater.
• A super annoying bug where Kotiloene kept falling from bridges is finally properly fixed.
• Some level design adjustments; most visibly, replaced one Kotiloene shortcut with another one.
• The lead melody of the main theme is now one octave lower, makes for a more pleasant experience imo
• Controller support: when a controller is in use, the "press a button to do a thing" messages show the corresponding buttons on the (XBOX-layout) controller.
