Awesome and addicting!

If you want to waste time that you could spend with people, then this is the perfect game for you. I've spent countless times playing it over and over, only to find myself back at the start playing again. The great thing about it is variation, the maps are randomly generated each time, and mystery pills are always exciting to use. Also, is it weird to describe some of the monsters as cute?


Different and fun

TBOI is one of the best indie games i've ever played, it shows good artwork and a new way to play a game without using guns, but with your tears.The game is roguelike and the levels are generated randomly, every run will be different from the last one, every level has a treasure room, with an item to help you manage to survive through the other harder levels, i've done 100% of the achievements on steam (before they added eternal ones) they are really difficult like the game,but when you get them you will feel awesome,a good choice if you can't spend soo much money and if you liked it download TBOI:rebirth.


Insanely addictive

This game is highly addictive and has a lot of replay value. The game has plenty of unique boss battles and items that make the game even more addictive and fun. Plus every new game has randomly generated maps and enemies, making each playthrough different and unique. This may be the greatest indie game I've ever played and would highly recommend it, especially for the price.

This game is terrifying, thought provoking truly superb. For what it is, it may be perfect. No game has ever had this much replay-ability so it is the bargain of the century!


Beware the addiction

So this is one of the first games I ever got on steam...I had seen it previously but never really read into it...I just new it was a dark, zelda-esque dungeon game. It sounded a bit interesting so when I saw it on sale I figured I'd give it a shot....Dear lord how addictive I've come to find it to be....After many hours I still found the game refreshing and new each time. But had the desire to upgrade to Rebirth. Rebirth being the same game but with much, much more, and new design I've spent even more time. The game is as hard as it is fun...There are so many enemies and items that can screw you in an instant. So enjoy playing, just don't get to the point you want to rip your controller/keyboard in half
