Got 4,71 € Steam Wallet. What shall I buy?

I bought World of Goo and it's a nice, relaxing, fun game. I would recommend it, even though i don't have full perspective 'cause i haven't played any of the other games that you mentioned.

Alice! (buy it in £)

I would go with Psychonauts.

BoI dlc :)

Psychonauts

Summer sale!

I would wait if I were in your shoes

World of Goo and BoI DLC are worth to buy. Personally I don't like The Baconing.

a condom :D

just wait for the summer sale

I'd buy World of Goo or The Baconing, the other games are good too, but I think they'll be discounted more in the summer sale.

If you dont know just Save for steam summer camp sale?

Binding Of Isaac/ Duneons of Dredmor

Psychonauts is an excellent game (one of my favourite). It's a lot of fun and the game is original.

World of Goo

Wait until the summer sale

get the BOI DLC

Binding of Isaac :D

Cake!!

4 and a half fortix.

You should probably wait for the summer sale as you'll have a lot more options for what you can buy then.

Bunch of Heroes?

Well, you can buy Limbo now.

Buy Limbo...it's just 4 euros :)
