Hi great work. Giana sisters and bubble bobble were one of my favorite games from c64 times. now the only problem with this kind of games I think is the controls. how we would make the player play this game with one touch with thumb only. I think I would make it by swipes going left or right or jump. for jump only option of swipe is advanced move of linear velocity in y direction upwards and with time out of 1 secs etc. It is too bad that we can not assign jump to swipe up. Other than that it looks great. I would make the game 1 screen tough not going up like original bubble bobble. btw check the game DROP WIZARD by Nitrome. They solved this kind of proble, with the wizards shoot their magic et each drop to the floor. it is not a bad game which brings back th nostalgia of old games like bubble bobble or parasol stars etc. Happy Gaming
