It's not likely for Summer Sweepers to get an animation update. It doesn't have a style that's easy to animate, and I will not have time to do it. Hexagum animated Monster Monsoon for fun for a year before we met, so I had a lot of stuff ready to go when we started working together. Even so, adding animations took a lot of time and effort on my part, the final release got pushed back by 6 whole months. An animation update for Bastion is possible, but even there it's more likely that I'd make a spin-off project than make changes the base game. For my new games I am trying to animate everything right from the start because adding motion afterwards is very difficult.
Thank you for your support, I am very happy that you enjoy what I do! I've got many more game ideas, so I intend to keep working hard to bring as many of them to life as I can!
