This game will be free forever as this is I recognize this is a starter project, I intend on expanding it a lot but all of the donations are voluntary, although I greatly appreciate donations, reviews like this are amazing as well, it keeps me motivated knowing that people want to play this game
Glad to hear it, i wouldn't be spending my time writing up a review or bug report if i didn't think there was potential here :)
While i think it's very cool to keep it free, i do think people should be compensated for their efforts, so my review is from the perspective that you'll be seeking to make a product people would gladly pay for, all games, even free ones, are viewed as a matter of quality vs investment, even if it's only time investment.
That being said, i shall wait patiently for your next update to see how this develops, good luck!
