Ok so it's a sidescrolling shooter. Like any other sidescrolling shooter it has potential because the base of the game is the same like any other sidescroller...
Make the enemies a bit smaller, make multiple types of enemies (each with their own different movement pattern), let enemies return fire, make ur bullets smaller, polish up the graphics -.-' , make the title screen a bit more attractive... and perhaps add some powerups (basic like extra speed or auto fire) start out with improving these points after u get the hang of movement patterns and return fire patterns for enemies it will be easier for u to make bosses (which is also very needed). I've seen better first games but don't give up! ^^
Peace
I guess its ok. Its really hard to kill yourself leaving no challenge to the game... playing with the mouse makes it even easier... uhm when the first boss shoots the bullets disappear... Oh it also took me a while to notice that the astroids hit me... and they also randomly disappear... It took me even longer before I noticed that that little dot randomly appearing around me was me getting hit :3 I guess this game does have potential but it needs some polishing. Keep the good work up ^^
The game itself has a nice flow the ships move around very smoothly. Unfortunately it offers no real challange, very minimal ship costumization and no powerups at all. The game looks nice though ships look good, the background looks nice. U might at least want to add Achievements and more enemies plz :3.
I need a force scroll... Add more to the mario game play. Koopas, running, jumping off enemies, fire flowers, Koopas, paratroopas, buzzy beetle (cannot kill with tetris blocks) and if you feel like it some bullet bills ^^
Now all you have to do is to make the lvls look good in stead of paint blocks... and make the space ship tilt when turning add a tractor beam so you can make lvls in which people have to drop the "whatever you want" (cow(multiple ones for added difficulty)) onto the landing platform add thruster sprites under you ufo and that would add to the gameplay ^^
