I was able to reproduce. I've uploaded a new zip. Let me know if works -- you really deserve the complete experience including custom wrapping paper :D
Alright! So! I got the same error... BUT! I was able to fix the problem. The .pdx has too long of a name I think for the playdate itself. I unpacked the archive, shortened the .pdx name to "gimmiefriction.pdx", repacked it, and it works like a charm.
I just tried to install 1.0.2 (version 6) on my unit (running OS 1.11.0) and I'm getting "There was a problem installing this game" on the device itself, when at 100% installing.
