"Growl" in both the arcade and Genesis had sub-par control IMO. It was a decent game at best, but the Genny port sucks. Definitely more flash than substance.
The thing that I hate about these coin-op compilations is how they make you realize just how much of a quarter-munchingly diffcult many of these games were. You try your best, memorize the patterns and whatnot, but still find yourself burning through "quarters" just to get to the last stage. Little to no strategy, just pumping quarters. RAAAAAAAAAAGE.
my main gripe with the TL2 version, the special move to knock away multi-enemies was hard to pull off. on genesis it was mapped to a single button.
