I know, but if it's a try and die game, the controls need to be more reactive, else it totally puts you out of the flow, I think it's the same for some of the stuff in my own game but here it was really not fun to play, and it's not a question of mood cos I played a harder game just before, and I enjoyed it in its generality :/
Not trying to blame you, I'm just saying you should maybe give more importance to the controls, tho don't spend 80% of your time on it like me ^^
