The wip tag makes the game not appear in the cdb ingame menu. You may get more exposure if you remove it.
This isn't true. WIP games appear in the menu
It may not be appearing for you due to the 5.4 only requirement
Removed the requirement since it works fine in the latest minetest version, probably an error on package creation.
I've been testing on MT 5.5 these days. I'll release a new version right now, I just wanted to make sure it wouldn't break. The API hasn't undergone any change that should affect it anyway. I might be less cautious with future MT versions :)
