Nice entry. Alhough a little buggy with the physics. Watercone got stuck at start of level 3, and doesn't fall from the first platform, so I wasn't able to continue playing :(
Sometimes both FireBall and WaterCone fall inside their own color platforms, which makes difficult to jump to another higher platform
But even with that, the game seems fun. Reminds me to FireBoy and WaterGirl, which I used to play with my son a few years ago.
Nice job! Congratulations!
Edit:
I don't give up easily, so I give it another shot...
Managed to pass the part I mention before, when the triangle got stucked, I jump and unstuck
Also want to add it has some issues with the resolution. Part of the level is offscreen (windows and full screen the same)
Now I can go in peace :)
