I am a very big fun of Besiege. I have been playing it since v0.15. I tried to install different mods but one of them was especially interesting for me. Of course it was Level Editor mod(http://forum.spiderlinggames.co.uk/index.php?threads/thecvbs-mod-releases-spaars-modloader.3342/) by ZiMMy. But now this mod exists only for old version of besiege and I can't use it anymore. But In my opinion it's a good idea to add Level editor to vanilla game ( or make a DLC) to allow users to create their own levels which will be playable for others. Players will share their own levels somewhere in internet ( steam workshop, this forum ), play others creations ( also there can be a system of activity points given for playing user's levels and weekly activity contests which offers winners to get some prises such as steam cards, steam keys or so on). This feature will be a good way to make an online part of this game . P.S. The visual style of the game is very suitable for Hololens( https://www.microsoft.com/microsoft-hololens/en-us ). I understand that development is very hard and I just shared my thoughts and dreams.
