https://github.com/jcornaz/play-jam-4/releases/tag/play-jam-4-submission seems to load on the device and start. Woohoo. You did not include a buildNumber in your pdxinfo, so anyone who tried it previously, it will not get overwritten with the new version. I locally edited the pdxinfo to make it work. I would suggest this pdxinfo that changes the name to be more descriptive, ads a non-zero version, changes the bundle id and updates the buildNumber (although since I changed the bundleId it wasn't needed)
name=LiftUp
author=Jonathan Cornaz
bundleID=com.github.jcornaz.liftup
version=0.0.0.1
buildNumber=2
pdxversion=20000
buildtime=753444725
It plays. It took me a few tries to understand I needed to use the crank to move the lift (the instructions are right there on github, I just didn't look outside the game :) ), but I think i understand how it works now and progressed a few screens. I will play and rate now. Congratulation on getting it working!
