Great "clone".
Is interesting how you implemented some techniques using the tools that GB Studio offers you, I also love that engine, I would like us to exchange knowledge and impressions ;)
I feel like some things really don't work that well, like the collision with the doors.
Menu done with point and click style feels redundant and unnecessary, and even awkward.
That boisterous and unclear ending looks rushed and like you've unfairly lost.
There are some things to polish, but I see myself occasionally playing this game from my console once completed, please continue and finish it :)
