I think this is real good for a first game. I think the UI and navigation worked pretty well. The art was also a highlight. There were some bugs that I found though, like being able to click on door twice and being teleported somewhere else. For future games I would suggest getting some playtesters so they can find bugs and you can fix them. I got to the end of the game but I do agree with Ryan that there could be a little more indication of where to go. You also could maybe increase the player's walkspeed a little bit, it felt a bit to slow. I also think that you could add a few more sound effects to make the game seem more lively. Overall though I enjoyed it, it's a real good first game.
