Roast potatoes
are the way forward. Anybody who disagrees should be cast out from society.
Anyway, I think Social Arcade is pretty good!
Jumping feels a little blocky, it doesn't flow as well as some games, like Mario or Braid.
you can also jump clean over the doors, which defeats the object a tad.
Maybe increase the walking speed, so the game plays at a faster pace. Perhaps add the classic bounce, when you land on an enemy.
But I very much like the concept. Hope you can implement a feature for custom graphics, that would be very smart.
I've also experienced a fair few bugs with the moving platforms.
Sometimes the collision just doesn't register, causing the player to pass through. Usually occurs when the platform is in motion.
Thumbs up from me though! Look forward to future updates.
[EDIT] About the jumping/movement, I think it has a certain charm. I'm torn between really liking it and thinking, could it be better?
It could turn out if you make the movements more like Mario, the gameplay would be worse. [/EDIT]
