Thanks much for the encouragement!
As a heads up, I have submitted an updated version to Metroidvania Month 9 with more content and upgraded graphics. If you are interested in checking it out, it's over here. I plan to do even more with the project in the future, though now that it's out of the jams, I don't have a projected time frame for when that might be. I'll be sure to let you know, if you'd like!
