That is an awesome mindset, great job. I know it can be hard to submit something you feel like isn't finished (or "good enough"), especially when people will be critiquing it. I also had a similar mindset, and I've been so anxious this whole time haha.
I'm sorry that your .pck file is missing (whatever that means), good luck with finishing the game though - if you ever want a playtester for a less unfinished version, you can find me in the shovel discord (same username) and I'll be glad to help :D
