I've just set up a Patreon for the game!
patreon.com/IcarusSunshine16198
I'll also be updating the game late tonight or tomorrow night. Sorry for the wait! Easter weekend kept me busy, and I also spent some time on making new maps (and a new title screen to replace the pre-made one)
Currently, the Patreon doesn't have any benefits, but after I finish planning for the update after the upcoming one, I may start adding benefits, such as gaining early access to new updates 2 days before public releases. I haven't full decided all the details for it, yet.
