$15 might be a bit much . . . but I do like the music. I'll keep it in mind next time I have something to budget.
Controls are ever so slightly finicky for the ridiculous precision it demands. Had to map up a gamepad, and it still gave me trouble - not the fun kind, so much. Things feel cramped, maybe? Movements too small, too fast?
But seriously, good luck with the making money on the internet! That would mean fancier games, in theory.
Dig it, but some variety in attacks would be nice. It's not the difficulty so much as the lack of strategy - in the console ninja turtle beat 'em ups, for example, one could fall back to well-placed jump kicks if ones health were low. Here, you just keep pounding on everyone for like eight years - and the character choice is between being fast enough for the parts that demand it, or being able to do enough damage to almost beat people in reasonable periods of time.
It was nice when I realized that the 'weak' enemies hit each other with their ranged attacks, that's almost strategy except that they do it as often when I actively try to trick them as when I just stand there.
Also, bombs are pretty useless?
You had me at space invaders, then lost me pretty quickly . . . stuck it out to the end, in spite of a hand cramp. Final boss was annoying with the unforgiving insta-deaths on screwup.
