I saw it, here is my comments:
You are using sprites for repeated images, which is not that great, try using either tilemaps or tiledbackground (the tilemap seems more designed towards what you are doing, since you are using a tileset anyway).
You are using letterbox scale, which is fine but most people that target mobile actually try to get rid of the black bars resulting by the letterbox scale
The controls feels weird, I don't mind the concept but the fact it teleports instead of just walking, while the jumping is fluid, just feels wrong.
You have 4 "on left clicked", you should try to see how to use subevents, to not repeat the code too much (it is ok in that case, but still more maneageable to not repeat unnecessary events), also I didn t know that click events triggered on firefox OS phones, i d rather use the touch event but it is fine it seems.
I can see seams in game, which could have been avoided by using tiledbackgrounds instead of sprites(since the tiledbackgrounds won t be spritesheeted on export), even though I am not sure those seams should even be here even with sprites.
Also the player can still fall after getting the cherry, but I am being too picky this time x3.
Your reply is full of criticism
Don't know why you do that
I hope you can change the tone
