Idea Shop suggestions

Here are some shop suggestions are the things you can buy now at the shop isn't a lot:
- Mega jump (On Smoke Monster): Give the player jump boost 5 for 5 seconds when clicked. This can give him a chance to escape the smoke monster when it gets near him. Also gives him time to see where to land. (Cost: 50 coins)

- Speed (Wool mix-up) Gives the player speed 2 for 5 seconds when clicked. This will make it so the player has a chance to reach the wool he has to get. (Cost: 50)

- Speed (Dead end) Gives the player speed 5 for 5 seconds when clicked. Can be used to quickly 'slide' in front of the other player to let them fall in your path. (Cost: 50)

-Double coins (all games) Has to be used before the game starts, otherwise the item will dissapear and appear in the next game. If the player wins coins in the game where he used this item, the coins will be x2. If the player doesn't win coins in the game where he used this item he lost it. Kinda like gambling. (Cost: 60)

I kinda don't know what the prizes really should be. So give some feedback on the prizes for the items.

 

I made it 40 coins because of this reasons:
1. It's a gamble, how less it costs, the more people will spend coins on it.
But I think I can increase it to something like 60 coins? Or do you think that's too much?

 

But 80 coins is more than you can actually win on those games. So why would anyone buy it then?

 

True, but those items don't give you a 100% win chance. I think 50 coins is a good price for all 3 as first place for non-Vips is around 40 coins.
