Hi! Maybe there is some confusion, Yulpers is already completed and released, you can get it for free here:

Yulpers Game of the Jam Edition is a planned expansion of Yulpers, which will add new enemies, areas, challenges, etc. and double the number of levels. Sort of a 'Yulpers 1.5'. Sadly, I must admit that Yulpers GOTJE has fallen on the priority list for a bit as I have so many other exciting projects going on and one in particular that I've been working on for waay too long and really need to finish for my own sanity's sake. But I do plan to get back to it one day. Hopefully the time away just gives my creative juices more time to stew so I can make Yulpers GOTJE that much better for you!
ps
If you liked Scarfy, I think you'll like Yulpers also.
