What an awesome experience especially since this is your first horror game!
Although extremely similar to The Crypt Terror, you did a couple things very different and with your own flavor! Those couple of things really made the game shine and I'd encourage you to keep fleshing out those ideas because you do have a knack for creating good horror. My only complaints of the game is because its very very similar to Crypt Terror, I feel like I had played it before. It was still a great experience and I LOVED your spin on the game!
Keep grindin and refining your craft man, I really do think you have a bright future in game making/development
Much Love
Stay Safe and Stay Positive
