Have you thought about expansions or sequels or anything? (I've read the "I have ideas for...", but the feel I get from the description is in the line of "I could, but-") I would say that as it is, it is quite nice and fun, and it certainly achieves what it sets out to. Nice work!
Additionally, as for tfgames.site - you could have someone else promote it for you as well. That's certainly not the only place to showcase it, or any future works you choose to produce.
