Show HN: Invertris (made by a friend of mine)

This is extremely clever. Well done!<p>Your friend needs to explain what the goal of this game is up front! As soon as I saw the video I got the mechanic immediately--but had no idea what sort of scoring system was involved. Normal tetris scoring doesn't seem to apply, because you can't clear lines. It looks to me like this is a co-op game, which was not immediately clear. If I'm correct, you want to last as many bricks/as long a time as possible.<p>You need to state very clearly that it's co-op and the goal is to stay alive for as many blocks as possible.

Wow ... that's the best way I've seen of making Tetris truly multi-player. It's not just competing against each other but actually requires changing strategies. Bonus points for the fact that the board is almost Escher-esque (<a href="http://www.mcescher.com/Gallery/switz-bmp/LW306.jpg" rel="nofollow">http://www.mcescher.com/Gallery/switz-bmp/LW306.jpg</a>)

You should tell your friend to remove any mention of tetris from the game description. The Tetris Holding Company is very aggressive with this kind of stuff.

Brilliant! You should do an iOS version and sell it.

It's a really clever concept... and simple too. Though, it's hard to figure out what the goal is, if it's coop or battle or other? It's really interesting to see what people are doing with it. Congrats anyway, impressive concept, love it. Buy me an Android phone, and I'll buy the game.

That's really cool. A unique twist on the concept, kind of like a battle. Anything similar for iOS?

This looks incredibly cool. I love these "new take on an old concept" games that actually introduce a new gameplay dynamic, rather than simply reskinning. Pass on my congratulations to your friend.

This is brilliant. I guess it would be almost impossible to complete an entire row. It would be cool if you got points for going "deeper" into the other side's area.

This is a really cool concept! Seems frustrating though.

Very nice. Good idea. Good luck, try to sell it.

What is the object of the game?
