Hi!
I really like Sonic 3D Flickies' Island Director's Cut, thanks a lot for making it! I've played up to the volcano stage, and noticed two minor things:
The faster shoe music and the invincibility music are buggy. The fast tempo of the former stays after the shoe effect is off, and the invincibility music stays until the stage is over. Maybe this didn't happen all times I picked those TVs though.
When inputting an incorrect password, it gets erased and you go back to the menu. Really annoying. I'd prefer that you get an error sound, then the possibility to edit it without having to retype it entirely.
Thanks again for a very fun game! It feels like when I got this for Christmas 21 years ago :).
Oh yeah, one more thing: if you die at a Time Challenge (for example touch an enemy when not having rings), it says Time Over :).
