While it's neat concept, the execution is a bit iffy. The art is simple, nothing wrong with that (though some rotation for the blue player would have been nice since the red one has it as well even if it doesn't really matter for twin stick shooters). The controls for the blue player were adequate, but not really satisfying, while the controls for the red, while they worked fine, didn't seem balanced. I think the red player would have to be MUCH more skilled to survive for any decent length of time as is. And aside from that imbalance, I think it's a bit too hard. While I understand that's kind of necessary for the concept (too easy means infinitely long matches), more time been spent on balancing it would have been appreciated.

I imagine the usual round should go with both players struggling against both enemies and each other until one player makes the fatal mistake which leads to the end, followed by even more rounds with ever changing strategies, but sadly it doesn’t really pan out that way due to the short length of rounds, balancing issues, and, since I played before the fixes, troubles with closing the game. The crashing was what really kept there from being any of that addictive desire to play 'just one more round' so I'm glad to hear that it's been fixed.

Despite that, it's still a neat idea that could use more polish, so keep at it!

Thanks for the detailed review, Craftsdwarf. I was actually really disappointed that I didn't have more time to balance it on Sunday given all the bugs I had to worry about. That said I've made some new builds to hopefully make it more fun. Since they aren't bug fixes, I'll provide them down here.

There are three main changes to this version:
- Turrents now fire more quickly AND over a longer distance, which should help balance them out a bit more. Proper use of swap is still necessary for success, though.
- Enemies are now spawned using gaussian distribution rather that random, meaning that enemies come in a waves. Numbers were tweaked to hopefully give a more enjoyable difficulty curve.

Mouse sensitivity was very low, and rather difficult to play with. The blue player's shooting would have been better with rotation, but all well. The art was fine. Lack of audio was a disappointment, but we can't all be awesome audio-creators ;). Lastly, hitting ESCAPE crashes the program all together. It was a good concept and has real potential though.

Lack of audio??? I had sound effects and music going (even if the latter wasn't very good…)

It seems it doesn't work well on Windows 7 64 :( It crashes at exit and audio daesn't sound at all. Anyway, I think it's a good idea, if a bit polished would be really interesting :)

So I jusst checked out the Windows build, and it's very, very busted. I'm gonna take it down until I can fix it.

Windows build re-uploaded.

Audio, mouse sensitivity, other stuff can be worked on the make it better.

It feels a bit unbalanced because only the red player can switch. Would have preferrd, if both player had somehow the chance to switch.

Nice Start maybe put a little more work on it definitely a base for a really unique game il give ya a 10 for originality
