When you leave a small gap, a message will appear below the playing field. Likewise, you will also get messages for clearing more than one line.
Trippy visuals include full-screen bump mapping using palette animation; software mode 7 effects such as rotations, zooms, and other distortions of the playfield; and lens effects.
The music used in this version is in a tracked format designed for use with Sound Blaster and other sound cards that use the AdLib chipset. It is internal, so it may be rather difficult, if possible at all, to rip it.
