I have played your game dessert stike, it's really well done, i have seen the effect with the bullet that has a scope ( really cool it's really useful for the gameplay to have a challenge, and not a easy game :) ). Nice design art, good work with the noise effect ( crash mountain, noise bullet, ... ).
I have one tips for you:
when there more than one ennemies, it's really hard to shoot them, so , if you want :) , you can make an invicibility with a timer ( 2 or 3 sec ), to have the time to shoot them, or make a menu with possibility to choose the dificulty.
So , if you want let your game and not change, it's your game, and your choice, I'm just here to help you.
PS: It's was fun :D .
