@remus - thanks! you have to export as HTML and name your file "index.html". Then go into the export folder, select all files and make .zip archive out of it. At first it didn't work for me because I was zipping entire folder, not the contents. Other than that I followed the official ludum dare html embedding guide which came to editing index.js file manually and replacing all instances of `'serviceWorker'in navigator`, `"serviceWorker" in navigator` etc to `false` (but I am not sure this step is necessary)
@candlesan @hugetube thank you very much, yeah I think this mechanic with exchanging multi-jumps for packages has potential, maybe I'll revisit it in the future after gaining some experience and skills. I've got some ideas for new levels where you could for example: pick up stones to put them on platforms to unlock doors, drop package/stones them from high enough to destroy some barriers, pick up packages that grant some kind of powerups/bonuses as long as you hold them, different boxes weightinig different amounts and impacting movement, boss fights etc.
