@mrpablington I'd never heard of this series before. This is exactly the sort of weird little puzzle game that I would have thrown money at if they'd been released in North America. The description on Wikipedia reminds me of some of the bit.trip series.
@GamesMissed I was obsessed with this back in 2006... I was importing lots of games from Play-Asia back then: https://en.m.wikipedia.org/wiki/Bit_Generations
