You can, if you'd like. That's what the recommended "Pay what you want" price is for. No pressure of course, but if you'd like to toss something toward the project, you're certainly welcome to.
If you already hang out there, you can leave a comment on post for this game on my FA, or just send me a note there. Otherwise, if you'd like to step away from the sea of general comments under the main game, you can comment right here, or whatever the most recent devlog is. Always glad to get feedback!
