So happy to have a Boulder Dash clone on the PD. Was a fan of the Speccy version. It's a blast to see it on the screen. The size / game play are perfectly suited to the device. I've had a little bit of screen flicker issue. Now and then, doesn't effect gameplay. Didn't notice the "lag" when on device did notice it when playing in mirror (slightly). Great work! Oh, I'm going to review it next Wednesday on Playdate Player. A channel even smaller than the Playdate :)
