Great game, nice throwback to the greats
And about 'phnmL' whose comment is a few below mine.
Just ignore him.
Crimsonland was released in '03, and while very maintained as a game, it is not the root of your game mechanic, even if you did or did not intend to emulate it's twist on a classic genre.
Both your game, Crimsonland, and even the BoxHead games also posted on Newgrounds are re-imaginations of arcade classics from the early 90s; Smash TV & Total Carnage. And if that doesn't make me feel like an old fuck, those games are reincarnations of an older game from when I was born;
Robotron: 2084.
Point being is that you can't be accused of stealing an idea from someone who has already stolen an idea, but you can however, breathe new life and reveal new aspects to an idea already known. If the former was the case, then every artist and musician would simply be a cheat.
And since people seem to find phnmnL's comment somehow 'helpful,' he's a narcicist. 'Plays the game on the hardest setting and complains he can't beat it. Like we're to believe that you're some gaming God who can guru your stupid ass through any game thrown before you? Of course not, you dolt... !
I only complain because he criticizes you for his lack of gaming skill. w/e.
Anyway, loved the music. Reminded me of Contra, and a little of Shin Contra. gj.
