Weird, but kind of cool.

As short and simple as it is, I love the mechanic of blocking a drain to exit a room. This could be the beginning of a really cool game if more was put into it!

Hey the instructions say Z to jump, I think it should say Up instead.

Short, Different and I killed some people nice try ^.^

...Did I just kill a bunch of astronauts?

I lol'd.

Hahaha, I feel this is a very zacaj game. I literally laughed out loud when I got to the end.

It might surprise you, but I actually thoroughly enjoyed it. And I have my own philosophical interpretation, so...

A simple suggestion that I think would add an interesting element of challenge to it would be if there was a time limit, so that you drown if you don't swim fast enough, making it seem even more that there's an exit. I think the effect at the end will be amplified this way.

I'm not sure to catch why I'm a villain, but nice work on the water particles.

interesting, the swimming was frustrating though, would have been cool if there was more to it than just pushing the ball in the drain.
