Neither interesting nor new, but fine.
I played through the game, but it was nothing new or interesting.
Of course, making a game this genre always is nothing new, but this hasn't even got any additional feautres, like altering difficulty. Maybe there could have been some more pictures, too.
Well, at least those are pretty well done, and it was a good and - in some certain way - funny idea to try out pixel art, but in my personal opinion, one is enough. When the second came, it was boring. Nothing new, again.
The coding should have been easy. No extra points here.^^
The music was quite good, it suited the style of art, especially 8-bit for pixel art. Sooner or later it gets annoying, but thank god, you can stop it.
You should have added a button when the "storie" is displayed on screen, so one can just click it in order to start the game or can take ones time to read all of it.
I guess that this is not a coding problem, but a problem of restricted TextFields. The TextField is restricted to Numbers, so it won't show extra characters like "-". The variable which is displayed in there still has a negative value.
Sorry if you don't get what I tried to tell you. I know my English isn't that good...
