Green Maze

You will have a path of 15 levels, the levels are divided into 1-5 where you have to find 1 key, 6-10 where you have to find 2 keys and 11-15 where there will be 3 keys. On each level there will be some features (spikes, attacking ghost, reduction potion)
I hope you will be able to pass all these levels and reach the end
