The user experience of the game could be improved with a few modifications. Eg. the intro sequence could be skipped when someone plays it not the first time. People usually expect WASD movement from sidescroller games. Implementing it would have helped getting comfortable with the game.
In the bedroom there is some bug, I couldn't leave the room. This is a good example to skipping the intro or having quicksave would be good to overcome softlocks.
If you are interested in creating storytelling games Renpy might be a good timesaving tool for you, because it's a game engine focusing on story games/visual novels.
Hope you will be able to fix the gamebreaking bugs and you can focus on the story of the game.
