It is your first game, so this is actually impressive. It isn't a great game and you know it, and that's fine. Very fine. You need to learn to walk before you run.

You may have not noticed, but in games things need to be very clear and evident (not easy, but easy to understand). The room with confusing movements isn't easy to understand, it is irritating. In the middle of the room add the inverted controls and that's it; the room did what you want (which was creating confusion) but leave it like that. Not changing every once in a while and making it extremely painful to get to the other door. It was a good idea.

The other thing I will say is, dialogs. If there aren't any voices, let the dialog be skipped by the player. Some people read fast, others not so fast. If the dialogs happen while moving, then those can be set by a timer, you got those right.

The audio was acceptable, and the visuals were acceptable.
I liked the choice of killing one or the other, with more time and skill you could manage to make a better game. This is all about experience and skill, which you can get, because about the other part... you just made a GAME!

I'll be frank, the game doesn't offer much variety and sometimes I go faster than the text which means I have some problems following the story. But damn, I must admit that I had a lot of fun playing and interacting with the characters!
