Before I say anything else, this is not a sequel to The Simple Arena. It's just a... simpler version of it. Okay, a better version of it.
And how's it better? It got the popularly requested (although this game isn't popular anyway) mouse control feature! It got backgrounds! The frustratingly low rotation speed got tuned up! Also fixed the bug where the music doubles when you quit the bonus feature. Hopefully now everyone can beat the first levels and don't have to grind, and can eventually beat the game.
Anyways, not everyone here may have played the Simple Arena, so here goes the real description of the game.
In The Simpler Arena, there's you, and there are enemies. You have to destroy the enemies and clear all the levels. Simple.
But is it all that simple? With 50 levels, 27 upgrades and 30 enemies including the 10 bosses, things aren't going to be as simple. Can you make your way to beat the final boss, Ultimateshooter?
WASD to move
Mouse to aim and shoot
1, 2 and 3 for purchasable active weapons (Mines, Stunner, Rocket Launcher)
Also in addition to bug fixes and mouse controls, I made backgrounds that are different for every ten levels, with the final boss and bonus feature fight having a little variation than the last one.
Also changed final boss theme into a better version of the usual boss theme, instead of just a slower version of it. That was lame.
If you find this game way too easy, you might want to try the old Simple Arena where you rotate by keyboard, although the only difference may be that The Simple Arena is more frustrating and less convenient than this one is.
If you experience lags, try closing other programs or browsers. Closing other tabs helps, too. If it still lags, maybe you should try to zoom out a bit (Ctrl + Scroll Down), the smaller it is the less it should lag. If it still lags, I dunno. If you really want to play this without lag yet it still lags after all that, maybe you should restart your computer and try again (although the chance may not worth the trouble). If it still lags, then maybe give your CPU a massage or something, I dunno.
