ACA NEOGEO Gururin is a tough recommendation, even for hardened veterans of falling block puzzlers. The learning curve is enormous, which usually isn't a complaint in itself, but it just doesn't mesh with the pick up and play nature of arcade titles. A lot of time is going to be spent fumbling around and not achieving much of anything. Given enough practice, and a propensity for thinking several moves ahead, players might be able to make some progress. Until then, don't expect to have a lot of fun.
Gururin is proof that sometimes the best puzzle concepts are sometimes met with a harsh dose of ‘average’. Despite doing nothing technically wrong, it sadly falls short of other offerings on Neo Geo like the previously released Magical Drop series or the still stubbornly Switch absent Puzzle Bobble series. As such it is only truly recommended to the puzzle fan with nothing else to currently play or the rabid digital Neo Geo collector. Everyone else should just let this one drop.
