I totally rate by the experience that I play the game, it doesn't matter to be a smooth control, it's more about the endurance of the bad move. If you have bad move, but you will pass anyways with the intergrity of sfx, music, aesthetic and mechanics, then that game will be high rated. Some game looks fantastics, but when you playing it, the control just feel so weird or the process to win is too difficult base on the weird control, that for me will be low-rated, but it totally depends on the game.
I have different idea to mention, I think some game is well polished because some developers spends time in polishing except to extend more design, I give up the platformer to make the game more focus on action to ensure my game at least has the smooth fight experience, so my game has only fight left with some unbalance data btw player and enemies, but generally it reach the point that I feels not a bad game, then I will go to implement some new stuff, that's the trade-off. However, for some game is just too good to make in ten days, then it's definitely pre-made.
