Monster Business is a 1991 vertically scrolling platform game developed by Eclipse Software Design and published by Ascon that was released for the Amiga and Atari ST.

[2] Crates spread throughout the level have bonuses that give varied positive effects to the player when collected, such as a temporary boost in jump height.

[3] CU Amiga criticized Monster Business's 'lack of variety' in its gameplay, but said it was "mildly enjoyable" nonetheless, calling the game "innocent fun in an uncomplicated way".

[1] Amiga Computing criticized the game as 'outdated' and boring, stating that it would be "more suited to the ZX Spectrum some six or seven years ago", and said that its playability "is just not there .. what starts off as vaguely diverting soon gets repetitive".

Amiga Computing expressed that they expected better due to the owner of Eclipse Software Design being a programmer with "close involvement with the project", but was disappointed.
