virtually perfect game tbh
really great looping map design and while the controls aren't as "tight" as later 2D Metroids at first glance, this places a large emphasis on planning and preparation for inexperienced players while high level players can take full advantage of its quirks and nuances to be an unstoppable tank
there are a couple "well how was I supposed to know that" moments but overall the design does a fantastic job subtly guiding you without ever resorting to holding your hand
