I dare say this is unfortunately the only TMNT Castleroid (at least to my knowledge), because Radical Rescue has some neat tricks up its sleeve for an original GameBoy release. Obviously, Radical Rescue plenty of technical limitations related to the hardware, and the expected gnarly difficulty at specific times (notably the final boss gauntlet).

That all being said, Radical Rescue is easily the best the TMNT had to offer on the original GameBoy.
