So, I just downloaded gdevelop and I have been previously using construct 2. 
I really enjoy using gdevelop 5, however, I noticed that it didn’t support multiplayer. 
Please add online multiplayer support as I may want to create games that involve multiplayer. 
I would say it is a pretty hard option to add, it calculates that Gdevelop is a free application, and it keeps that for the already huge costs of hosting services if you then want to add even the costs to buy multiplayer servers really becomes a expense Too large.
However you can expect other opinions perhaps said by more experienced people.
It’s never too late to share some knowledge with others
You can achieve online multiplayer on your PC/Android games easily with Parsec. Just implement the local multiplayer and then go online. The hoster, however, has to have a good connection to share screen with others. But hey, it’s something!
