This was really fun! I enjoyed the simple design and the premise was good too. I'm curious as to what engine you made this in? I'm in the ever ongoing process of learning Game Maker, and I was wondering if you used it?
Thank you, I'm glad you liked it!
About the engine... well, it's not Game Maker, nor something publicly available.
It's an old and deeply customized C++ engine I keep maintaing throughout the years.
I still use it because, compared to other engines, it's the quickest one to develop interactive ideas.
But Game Maker is cool too. 👍
