- I see that you tried to do everything by yourself, it’s a good initiative
- good choice for engine

some mistakes to avoid:
- The text is not very visible: you have to put it in a dialog bubble, put in a color that stands out (black)
- We see objects, it makes us want to interact with them, but it’s not possible
- it’s very yellow, TOO yellow. Putting a floor of a different color or texture will make the game look less 'flat'.
- Don't hesitate to use assets (crediting of course) so you can concentrate more on level design and programming
