It's pretty much Galaga in game play, but there's an interesting twist to it, the patterns of your enemies (and some of your weapons) are based on the music played. I started off with Ockham's Razor and it was a nice predictable run, moved to Abney Park and it became a bit more challenging, switched to Disturbed and it went crazy, then I picked up a "Subwoofer" weapon and moved to Tech N9ne where the screen was filled with huge blasts based on the bass of the song. The way this game changes based on what is played gives it a definite replayability edge over other similar games. The boredom didn't set in after a few hours like it normally does with the loosely related games I've played.
A little short on documentation, but once you've played for a while everything works itself out. The upgrade system took a while to figure out, even movement and character selection took a few runs to get down, but it's definitely worth taking the time to muddle through. Definitely a game worth picking up, just a shame it didn't show up here until I'd already bought it on Steam.
A platformer that isn't a fluffy kitties and rainbows. If you spent far too much time playing Rygar on the NES this is probably the game for you. The boss battles are a lot harder than anything from there, more like some of the more difficult bosses from Act Raiser, but Volgarr is completely fair in its repeated slaughter of your little viking. I'm glad it showed up on sale, I probably wouldn't have bought this if it didn't, but now that I have I'd say it's worth picking up even if it isn't marked down.
I'd like to point out to a certain someone below that needing an account, which is only available using a key from buying the game, to play online is not really DRM. You can still play it just fine without being logged in. You can install it on as many computers as you have. There's just a login for online play and leaderboards. As far as the game itself goes I'd love to see a better method of getting upgrades than playing through countless incredibly strange achievements. I can imagine this becoming a real pain as you get closer to level 25 as it's already starting to slow down a lot and I've just hit level 12. I've only had it for a little while, so I've only seen a few of their daily levels, but both of them have been a lot of fun and varied. One was a mostly ground based slalom course, another was based on staying up off the ground and twitching through tight obstacles. The user levels are a real mixed bag. Some are wonderfully made, others are incredibly bad and even use colors that are painful to look at. I've already shared this to G+, and I don't often (the last game to get that was The Witcher) do that, this game definitely earns my recommendation.
The control scheme always annoyed me, it seemed a bit like DDA on crack. I found it incredibly hard to play with keyboard/mouse, but it worked just fine with a PS2-like controller. I have never seen a QTE game that really worked for me, but some of the events in Fahrenheit (especially towards the end) were nearly impossible to keep up with even using a controller. The ending was strange, and definitely took it in a direction other than where it seemed to be going, but even the worst ending (unlike the best of Mass Effect) left an opening for you to continue fighting for the ones you loved. From what I've read the GOG version is the unedited one which removes some of the strange choppiness from bits that were cut. While true that the editing didn't remove anything from the story, it did have the same slightly jarring effect as blanked out words in songs on the radio. I did originally play this on Linux using WINE and it worked perfectly for me, not sure about the version here though as I had the disc-based game. I am most definitely planning to pick this up as a digital release, even with the disc version, when it goes on sale tomorrow. Here you get to bypass that obnoxious copy protection which, oddly enough, gives me more trouble on Windows than it did on Linux.
