EDIT: Nevermind, these "suggestions" are both just me figuring out how pulp works. Thanks to the replies that corrected me!
I am still waiting on my playdate, but I am getting into basic programming for the playdate now, and I'm loving Pulp despite the limitations. The "launcher card" is pretty useless for me right now though, as the simulator only loads .pdx files temporarily and doesn't add them to the simulator's "games" page.
Currently the sideloading webpage says you cannot sideload without registering a Playmate because there is nothing to sideload to. In my case, it says these even with a simulator registered to my account that could accept sideloaded games.
To be frank, this feature would only really be helpful to casual developers who do not have playdates; I assume any serious developer would buy a scalped playdate in order to be sure their game runs at a reasonable speed.
Still, I think this could be one of several features to improve the Pulp exporting experience. It would also be helpful if the savedata from your test-plays did not by default export to .pdx with the game itself. I assume there must be a workaround for this, but it is pretty annoying to send a friend a copy of your game and then realize that they're starting partway through.
I'm very new to this, so these may be features that are already available that I am not using correctly.
