great game, it is a unique take on a survival puzzle type game. (you should change some of the tags, some are not related and Puzzle is missing)

This is so difficult but the gameplay is good.
Art is not very good but that's ok

This is a really good game with a really cool concept! It's simple, yet difficult and unique.

It's definitely an interesting idea that I'd like to see get expanded further. Like sekru said, very good concept for one hour, and I like that I'm trying to figure out what the consequences of going right or left are, and that they change every level. Some of the levels are beaten too easily by nudging back and forth without consequences, so there are some design bugs to work out that probably weren't possible to fix in the limited time. Overall very interesting, but it needs some more work to make it an engaging game.

It's nothing special, but for something made in 1 hour, it's at least unique.
