Alright.. I'll just jump-start this thread by giving general feedback to a random game, the HTML game Rogue to Ruin:
I like the simplicity in the graphics and the gameplay. I recognized the art and understood the mechanics instantly. Like many others I think this game would work very well on mobile because of this simplicity and the vertical view field. All the interesting pickups make me want to just keep playing. I should have picked a game that easier to criticize, I don't really have anything constructive to add.
I could use some feedback on my finished game Catacomb Chess (ZIP-File unpack and play). Mainly on if the gameplay mechanic is enjoyable. And maybe what you liked and disliked the most about the game. Would it be worth $1,80 or $2,22 in your opinion, or should it remain free?
