Yes. Keyboard response is not as good as I want it to be. I've had no time to redo the keyboard code to optimize it. I've used the "trick" to make a BEEP whenever a key press is detected. But I know that's not enough.
Will try in future versions look around this problem... and others the game have. The game is "crude" but playable. And I want to attempt, in the future, to convert it to "machine code", perhaps via a Basic compiler, to speed up things.
But now is time to try all the games people has submitted to this Jam! :D
Thanks for the feedback!
