I quite like this game! Sure, it's not traditionally entertaining, but I like the message you guys were trying to tell about people who struggle with depression or anxiety (at least, that's what I'm assuming this is all about).
Next time, though, maybe make what the player's supposed to do a little more clear? It looks like a lot of people are confused as to what the life bar is and what they're supposed to do to reach the ending. It took me a while to figure out too, and even then I wasn't really sure as to whether or not I was playing correctly.
Overall though, this is a pretty good first game! It's simple, has a message (even if it might be a bit unclear) and the art is cute.
