Download free demo
Install Steam first for Windows and OS X demo downloads to work correctly!
Current (v 124): Windows Linux OS X
Download size is about 66mb. If for you current version fails but some older version runs, please report that me by mail or skype, all chances are I can fix it really quickly, if you provide enough information for me to reproduce the issue.
MP3 support: out of the box on Windows and OS X using codecs included in the operating system. Under Linux, please install libmpg123 or better yet just use OGG instead. MP3 is a patented, non-free format; this is why neither I am not your distro maintainers could provide you with an out-of-the-box MP3 support. If you use Linux you should switch to OGG.

Note: the free version has only 11 arenas (full has 36) , does not support saving of images and custom arenas from editor, and (most importantly for me) it does not directly help me pay my bills. If you like the game a lot and want to have more arenas to play, or want to use editor as artistic tool, and have some spare money, you may want to buy the full version.

The game is updated quite often with new bugfixes and features; I do not want people to download ancient versions which have issues that I have already fixed.
Review guidelines: In a review, please provide links to official pages. If you're writing review in diffrerent language, and really need to hotlink the files, you can hotlink them, but near the hotlink(s) you must have a link to this official downloads page, explaining that there might be a newer version available through this page. You may freely use any screenshots from this game you see on my site, and quote the content, in context of review - but you may not imitate or spoof this site. If you feel you need to store a copy of the binaries on your site, please contact me to discuss it.

System requirements:

Recent drivers. If anything is wrong, first try updating the graphics card driver.

Video memory: currently, 256 MB seem to be the minimum (let me know if it runs on 128), 512 MB recommended for big screen resolutions. I'll try to lower requirements to 128 MB if I can.
Known to work on following video cards: NVidia GeForce 9800, 9500, 8800, 7600, 5600(?), 280, 295, and other similarly recent NVidia cards, ATI Radeon HD 4650 (512 MB), 4850, 4870, 3800 (With recent drivers. Drivers older than may 2009 do not work), and other similarly recent ATI cards. If it fails on such card, first update the drivers, if it still fails, send a bug report (as described in readme), if a card is indeed good and has the required features, there is a very good chance that I can fix it in same day.

Known not to work on following video cards: most onbroard graphics (in particular GMA), and old cards (in particular Radeon 1300, 1600). These cards lack required features.

Known issues:

FPS stutter on dualcore with nvidia or ati cards. In your video driver options, look for "threaded optimizations" or similar option and try disabling it. It was broken in older drivers, and may still be broken now. Also, you can try choosing Arbitrary framerate (in display settings in Polynomial), or set CPU affinity for polynomial to 1 core.

On OS X, if video card has 256MB of video memory, full screen may seem to 'hang up' either just the application or entire system. The current best guess as of why it happens is that OS X gui (which is drawn using opengl) hangs up entirely.


q: Does it work on 64-bit processor or 64-bit operating system?
a: Yes. 64-bit Windows is fully backward compatible with nearly all 32-bit applications. I have positive run reports from people using 64-bit processors and operating systems.

q: It crashed on Vista/Windows 7/amd64/quadcore
a: There is no known incompatibility with those systems or CPUs. Most likely, your graphics card or drivers are the problem. Please try updating the drivers, then if it still fails to run, report the bug to me.

q: Can I review it?
a: Yes, you don't need any special permission to review it and link to my pages. However, if you wish to host a copy of the archive, or hotlink to archive or installer file on my server, you need to ask for my permission. I am updating the game quite often, with new bugfixes and features.
