I'm glad you liked it! It can also run on the original hardware (btw, the thrown items are too small, I will need to fix it...). That console still has some untapped potential, I will try to squeeze it. :D
That is cool that it works on a real GB. I looked into some of those GB editors, they look great I just need to commit to making a small game and see how it goes. The GB aesthetic lately has been enticing to me.
GB Studio is easy to use when you understand its limitations (colour palette, sprite size, etc.). It's also good for prototyping or laying out simple concepts.
