This is really great for your first game, great concept. The main screen where it has the options to “Play, Quests or Exit” it could be cleaned up a bit more. It all mashes together, maybe create buttons so it is clear. Also where it says “Level creator, coming soon” make it so Level Creator is the same font size as “Play, Quests and Exit”. Then below in smaller print write coming soon. I’m playing it on a LG nexus and when I hit “play” and go to the next page, on the next page the home button (bottom left) and then trophy image (bottom right) are cut off and I can’t see the whole image. Tutorial is also spelled wrong on that screen. I like how the level turns green after you have passed it, I don’t think there is a need to put a check mark on top of the number once you have passed the level. Just turning it green shows the user that they have passed the level.
Level 1- Good, maybe you should make a quit button and pause on the level screen in case the user wants to go back to the home page or if they want pause. In the tutorial you should also show the user what the blue smoke means. It is clear that you want the money bag but I didn’t know that the blue smog meant I would lose a life.
Level 2- I like this level, maybe choose colors that are more contrasting because when you are leading the orange it is difficult to tell where the wall is vs. the background since they are both very saturated colors. Possibly try a brighter red. Also add some sound effects for when you die, when you transport, when you collect a key, etc.
