Indie Game Recommendations

[Avalanch3]

Hi guys, my Steam Library is a little thin on the indie side of gaming right now and I was wondering what indie games are top dog right now and which ones I should seriously consider buying.
So far in my Library I have the following indie titles:
Awesomenauts
Braid
Don’t Starve
I’ve shortlisted Spelunky, Mark of the Ninja and Monaco: What’s Yours is Mine on my wish list and I’m hoping these will be included in the next few Steam sales.
Could you guys make some indie title suggestions and explain why you have suggested these above others. Sorry as you’re probably sick to death of discussions like these but I would be hugely grateful if you could help. Thanks in advance :)

All 3 of those titles are very good in their own genre. You can hardly go wrong with any of them assuming you understand how each game works within their genre.

The Binding of Isaac and FTL, really good Rogue-like games but for BoI at this point wait for rebirth

I agree with illusiongamer and his suggestions

If you are going with Indie games you gotta have Super Meat Boy. I loved Bastion. Fez was fun but challenging as hell. The Stanley Parable, Dust, Hotline Miami, Thomas was Alone, Limbo, and Antichamber are all also games I enjoyed.

I see that graywolfe42 has listed Dust, I have finished it, I think that's a really good game, I've had a lot of fun playing!

These are a few good ones:
The Binding of Isaac
Castle Crashers
Super Meat Boy
