thanks for the feedback!
--> i still need to learn more about health system to make it appear in the screen, i also got some problem with screen resolution, that heart on screen just to make it look good, it has nothing to do in the game
--> yeah, the enemies and the gems color looks bit weird, cause i want to make it like weakness in pokemon(fire(red) gem beat grass(green) gem etc) but i dont know if i can change the color, so i make it same according to the source
--> yeah i think that will work! at first i also thought about enemies attacking from many direction, but i got a lot of problem in my code, so i reduce the direction and make the enemy only appear from left
--> good idea, i think it will make the gem movement moving more smoothly,
i appreciate it dude! thanks for playing !
