Do you think 2D platformers with anime sprites are still viable? I've been thinking of making a platform with Sonic physics set in the slippery snow, except instead you play as a cute armless ice skater who has to fight by slashing enemies with her kicks. The world would be a fantasy environment that encourages you to explore like Donkey Kong Country 2, and the gameplay would punish you for misjudging your speed or timing as you burst through ice walls.

I am concerned that the current generation only cares about Unity engine and 3D games. I might not even be able to break even if I ever sold the game, and to be honest It's hard to motivate myself to make it if I'm just doing it for free.
