Thanks for the ultrafast v1.2 update, very nice!!! Now the aiming definately works better, with this bigger dot and together with the setting "short" for the "aim line", the game plays perfect then. This is how a Puzzle Bobble game should work. Great.
If I were you, I would make the setting "aim line short" the default setting, because normally these kind of "Puzzle Bobble" style games, should be played without a long helpline, because the user should also make mistakes in aiming from time to time, it's the game principle to do so and this is nearly impossible, when a long aiming-line (I call it helpline) is visible. But such a longer helpline is okay for absolute beginners, therefore it's selectable in the game-menue then, but I would not make this the default setting, if you ask me.
And another thing I found out in v1.2. The settings "aim line short" + "aim style doted" end up in the same result as "aim line short" + "aim style line" (because there is no visible line in "short"). This is a bit confusing for the users, because you generally expect something to change, when you adjust something in the settings. But this could simply be solved in a way, that the function "aim style" is greyed out (unusable) in the moment, when the user selects "short" for the "aim line". And when greyed out, always the word "doted" should be visible, for "aim style". Then everything would be totally clear for the users and there can be no more confusion, regarding this point.
