This is an absolutely stunning ROM hack. It has a level of polish with the artwork, gameplay and sound that, in combination with the liberal use of graphical effects, make it feel like an official, late release, Mega Drive game.

This is a relatively short hack but it makes up for that with it's fair but difficult challenge. This extends to the bosses, which are well telegraphed and have attack patterns that are easy to learn whilst still offering a challenge.

Definitely give this one a go, there are difficult options to help you find tune the challenge if you desire them.
