This is just binding of isaac.
72 hours? Thats not a ludum dare game. 48 hours is the limited amount of time. unless its 24 hours.
Actually, there are 2 events on ludum dare, competition that is 48h and you have to work solo, and JAM that is 72h and you can work in group.
Somewhat good but weird ._.
i know, some bugs popped out last minute :/ and we didnt have much time for balance it, but remake is coming, improved and better ;)
For 3 days game turned out to be awesome :P. Guys, if you are interested there is second ending... Small tip - 60 times 10 seconds.
