Trizeal

Trizeal is a Japanese shoot 'em up arcade game developed by Triangle Service.

Dreamcast version

It offers a score attack mode, a sound test mode and new stages that weren't in the arcade version.

Although this game is a Japan-only release it is quite "import-friendly" as there is some English displayed during game play.

The game was made by only three staff members and the console conversions were handled by only one person.
