I had the same thought about just playing tetris well being an optimal strategy, but by that point it was too late to make major changes to the project (and I couldn't think of a mechanical change that would prevent the issue).
What about the controls felt odd to you? Personally I am not completely happy with how dropping the pieces works, it is faster then I would have liked and I think it would be better if holding it down did not persist when a new piece spawned.
Thanks for the comment and for paying!
