I used something similar like Game Maker (called Construct 2), so a simpler 2D enginge. I think multiplayer won't work now, since I would have to rewrite so much.

I started my Game already before the announcement of Construct 3. Also, Construct 3 ist WAY more expensive Witz 90€ per year instead of 90€ one-time purchase like Construct 2.
As I am sure that I won't use Construct for that long anymore, it would not be worth it.
Hm, that First Bug sounds interesting, I'll need to test it myself.
The second one is known already, I guess I was too lazy to fix it since it is quite low impactfull. But easy fixable in less than 2 minutes.
