The ColecoVision conversion of Boulder Dash is really quite wonderful. It was converted by Micro Lab and published on the Microfun label in 1984.
Graphically the game is well-defined and nicely-coloured. Gameplay-wise it is responsive and rewarding. All the classic Boulder Dash levels are present and correct and the programmers have resisted the temptation to redesign them.
For my money: one of the best games on the ColecoVision console. Boulder Dash generally works well on whatever format it is running on, and this ColecoVision version is the bee’s knees.
