Just played and voted. Pretty fun, reminded me of that old flash game lava boy and water girl. One criticism I have is that when you press the down arrow, the whole page scrolls down which makes gameplay difficult.

Hey hey! Constructive criticism coming your way:

• Does the screen have to be that small?
• The part where you're climbing the stairs of alternative elements felt really jank, probably because the window in which you can switch is comparatively small for that section. I got it eventually, but it was more of a difficulty spike than it really needed to be tbh, especially cuz the section after that is way, way easier.
• I'm sure you noticed this, but the game could use some sound :/
• This could be because of the black and white, but it's really hard (at least initially) to tell the difference between what's presumably water and fire on both your player's head and the ground.

Overall though this game plays a lot better than others I've seen! Just wish it was longer :(
