Hello everyone,
this is a post where i will write all my suggestions and you can write them also in the comment.

Website suggestions:
we can see who our followers are, we can see who downloaded our planes, show us statistics of our game like how many planes we shoot down in sandbox mode or the best time from the challenges, extra section for modder.

Game suggestions:
better crash physics, a tutorial how to build a car, three corner fuselage block, Ship part-> how to build a ship tutorial, helicopter parts-> how to build a helicopter, maybe a map editor-> new section in the menu maps-> editor/sandbox-> try it/free flight, the option to switch between cocpits->new button in free flight, parachutes, ejection seat with dummy(maybe something like self destruct),more engine models/rezisable engines, bomb parts that we can build our own bombs for challenges

challenges:
more fun challenges like build a glider look how long it flys,build an bomb (look game suggestions) and destroy something,

Multiplayer:
i know its hard to make but hellfirecoder and unstableorbit have already maked then you can make it too,
now my idea:a new menu section->pc/mobile-> when you click on mobile you can change the map the normal map or one big or one small rhe same on pc->servers you can choose between the country england/germany russia, you can also choose between the max of parts like 50/100/150.....300 and you can choose if weapons are allowed or not you can see them but you cant use them->you choin->there is a new button in sandbox the chat button->you can ingame change you plane maybe you must land or crash than you can type in the chat "change plane" choose one and fly there must also be a restart button "repair plane", you cant change the game/quality

i dont need any upvotes but it would be cool if you upvote it so the devs can see it and let me know if i forget something you an also add things in the comments

thanks for reading this birdsofsteel
