i found something isn't nice. when i beat some enemy, the coins are go near. but i cant distinguish correctly between coins and enemys attacking. it still a good gameplay though.
need x coordinat limit. need some visible enemy. need the rightly tigger on the ship to shoot. need your own preloader. need some challange. and need to improve. yaa, thats all my issue i've got.
Sorry, I know my sprite work need heavily improved. Noted for next update! btw: ummm, that's not coin. That is bakpia.
