It doesn’t run that well on my computer around 55 FPS but not very steady (sometimes it freezes very shortly, perhaps GC).
My spec are Athlon 2500+ with GeForce 5600.
Additionnally the fullscreen pictures (title, jack’s jouney, option) have a small bug (horizontal and vertical buggy lines, I will post a screenshot if you want). I don’t have this problem when in window mode.
The applet did run better (the FPS was steady and I didn’t get the weird lines but this is logical since it was not fullscreen).
Hmm, there’s a bug in the JWS version (not in the exe) I thought I had fixed that problem… (the game contains a buggy patch that prevents screen rez change, so you don’t play at 800x600 but at your current rez).
I’m going to upload the correct version now. thanks for testing !

Yes, well deserved Lilian!
I submitted Lost Drops too but unfortunatly I was told that graphics and polish are lacking. This is not surprising since I’m not a graphics designer obviously.
