Thanks for trying, I'm glad you're enjoying it. To address your comments:
1). I don't recall ever hearing any pops in the music, testing on ~4-5 different Symbian phones of the time. But I never tested on QD specifically as I never owned one. It is a slower tempo song than most of the others, I can confirm that much. Was slower to set the "downer" tone of the story.
2). I agree about the slow transition time.
3). I don't recall enough about the controls as I haven't played in years, but we found them serviceable enough to play through to the end.
4). The ZIPped installer was provided because many web browsers of the time, by default, tried to display a SIS file as if it were a web page, rather than opening up a save dialog. It's mainly still offered as a ZIP in case someone's using an older and / or more simple browser.
Being the first fully original game I ever produced, it's far from perfect but I'm still proud of it, and it's nice to have someone playing it all the way into 2021.
