I'm so happy that you've enjoyed the game so much, it means a lot! I'm planning on releasing a small update next week, but after that's out I'll get to work on Reine 100%.
I'm not sure if I'll end up making stage obstacles, at least for the current lineup. But it's a good possibility for future Beasties!
Also, since you asked about Patreon, it's completely optional and the game will always be free! But yes, a link is on the title screen :p
