I should post this here instead :)
In my opinion, there should not be that much text just to explain how your game works, i think that is bad design. The game should explain itself in gameplay, or give a explanation once as the game starts, and when a new thing occurs. I liked the gameplay in general but i dont like that you need to watch to the right and left back and forth all the time, maybe it is just me i dont know, It started to hurt my eyes abit and was a little confusing at times. In the start menu you should have the text START GAME or something, not TASK. Not that fond of the music, it sounded very generic. I could not switch to full screen, do you have that option anywhere? This game could be better with some more time into it! :)
Edit: i just saw that F4 was fullscreen, so dont mind that :)
