15$ to spend on games what should I get?

Essentially just the topic but I've got $15 left this month for freetime and seeing as how the humble bundle has a huge sale going on I don't know what I should pick up. I'm looking at Banished but not sure if it's worth it as from what I read it doesn't have a real endgame and just a general survival. I'm looking at PC games or PS4 including 30 day rentals of ps+. I know I could save up money to shell out for something big but I'm looking for more of a quick satisfaction boost since I've preordered and paid off most of the big games coming this season. Any suggestions? (sorry if wrong board, haven't posted for a while)

Roundabout (Steam is down right now unfortunately)

I assure you it is the greatest game to ever feature an official eSports mode commentated by a skeleton.

Also @fobwashed is in it!

Shadowrun Returns, Machinarium, Steamworld Dig, Monaco, Nidhogg, Risk of Rain, the Amnesia games, Outlast, Far Cry 3, Tomb Raider, Volgarr, FTL.

They're all good, they're all very affordable right now in the Humble Store.

I'd pick Shadowrun Returns and Tomb Raider I think.

Final Fantasy IV! It's on Steam now!

Also Steam appears to be down. D:

Child of light or Transistor

Shovel Knight's pretty good.

Take 10 of those dollars and spend it on the humble indie bundle 12.

Hotline Miami, Shovel Knight, Counter Strike: GO, just to name a few.

Jazzpunk.

I guarantee that it will boost your satisfaction.

Everyone should own Rogue Legacy. If you don't... do

Mark of the Ninja is fantastic.

Dust: An Elysian Tail is also pretty great.

MK9 is only 5$

Just saying.
