No, just no.

Not bad game,with more things this can be a good game,but i know its prototype still.I think with some good ideas you can make the game better.

I will give you some ideas :
1.More souls :
Add souls what are blue,you can still collect it,but it slow you down a bit.
Add souls what are red,you can still collect it,but it speed you 2x times
2.The platform :
Add some obstacles what can made this game harder,maybe lantern,or a hallowen pumking.etc.
3. Difficulty :
Make a difficulty setting,like : Easy,Medium,Hard.If you have good idea for a name of a difficulty like "baby,noob,pro etc." add it,its cool.

simple and very nice background! ;) keep it up!
