Thank you so much Nathan! We also want to make a full fleshed version eventually! We started shifting to a more indie career this year, and we just announced our new game, which is also a tower defense (completely different than TowerBag, but very unique as well). If this catches your attention, we would really appreciate a wishlist on our page! Also, sorry for the late reply!
