There is now a music control! Nicely done! Are you going to implement a pause feature? To be fair in my review, the art is very nice, the animation is very smooth, and the game play is actually really fun for a simple side-scroller. It really is a well done game, and with a few minor tweaks could be very good.
Not a horrible game. Not very polished at all, though. I would recommend either ditching the need to steer with the mouse in favor of a keyboard steering, or at least all the option. The need to click on the ship's wheel to steer is not really obvious, and with out speaking the language (Dutch?), I cannot read the instructions.
Not very well done for the mobile platform. The buttons necessary to build units are way small, the menus do not fit the screen well, and the code is sluggish. Even on a pc, however, it would be annoying to have ranged units that cannot fire past melee units.
Thank you for your advice, you let me see the game deficiency
