Nice little puzzle platformer with a story. Very cruel bad ending lol.
Some personal thoughts:
-The turbines/bubble interaction feels a little weird. It starts to go downwards when you stand on top of the bubble, followed by a delay. Only then the bubble will get blown off by the turbine.
-For some reason, there is a weird speed difference between walking on ground and maneuvering in the air. Walking on ground is way faster, which threw me off sometimes when I hold directional button in the air and lands, especially on small platforms.
-Since there is only one transformation, I think it would be more straightforward to use Z as summoning bubbles and X as blowing fire (character can still switch colors based on last ability used), instead of using X to switch mode.
-Would be nice to have ability to skip dialogues.
Good job overall, thanks for making this!
