Very cool game. I like the different moves the character can make with only a few buttons. That combined with the versatile behavior and reactions of the basic enemy also provides great depth to gameplay. The large amount of bosses/subbosses is great. The humor expressed trough enemy emotions and never repeating background animation is also great.
Too bad only one level is free and it is the only level officially available for PC players, it is ultimately short. I have played it so many times over the years.
The full game needs to be released to PC officially otherwise PC only players will use emulators and not buy the full game. I am all for paying for developers work, but have no desire to buy a console, something I consider an outdated technology.
