Really love this game! Great colour and style, fun and challenging gameplay.
Reminds me a little of The Flame In The Flood, but in a good way, not derivative at all.
I don't really understand how the cages work.
I'd love to see you expand this further - Saveable progress maybe? and multiple levels with different challenges? or at least have a leader-board so you can try and beat your best distance.
Great work!
