While just being a second game could mean more experience than I think...That is amazing for a new developer. You've really got something good here, I'm sure you could made some change on the side with this one, and possible a real income if you keep up your diligence.
I have had many hours of fun with your efforts, so I looked for a donate link to throw you a tip. There doesn't seem to be any that I can find here or in the game.
I hope to see more of your work in the future, be well.
