Option button in main menu doesn't work. It will be great to have a back button in the character choosing screen. Also for some reason I can start any mission I want (not only first) but there are no other missions, game only starts the first level. Also I have infinite number of lifes and final screen of the level shows my score as AAAAA and total points as 9999...etc. After pressing ready button on the score screen the game shows me the main menu but score screen shows as well so I should press ready button again to have access to the main menu. I know it is just a beta and the game looks good but I hope my feedback will help you. Good luck!
thanks for your comment, the demo is a short one, the game will feature the full set of levels, but this is a demo to show the game progress and allow you to play it.
Regarding the ready button I'll fix it in next update. Thanks for pointing it out to me.
New version has been submited. with issue fixed.
