Sooooooooooooooooooooooooooooooooooooooooo, You have a lot already, but I want you to listen to the next following things:
Relocation of Items (water purifier/cooking statin, etc)
You should make it smoother -- Don't ge me wrong the game is AMAZING and I believe it has a lto of potential, just it is laggy on some PCs
Make it harder (eventually) - - You should be able to add other things like 2 sharks, or less items etc (EVENTUALLY) don't make it impossible to play
Have some tips...like I had to try a lot of things to understand how to make a second floor and why we could make pillars....and I have to admit, pillars are very important
Add hit bars -- (on shark and on your foundations because sometimes you think you will get there in time but you don't
Add informations --- (have a brief description of what each thing does)
Multiplayer option - Self explainatory
Throwable objects - Already explained
Some of them have already been said, but are great ideas
I honestly think this is one of the games with a lot of potentiall that I have seen. This is a very created game that presses you to watch out of your surroundings. It is a mix of creative and survival. I believe that this game is great as it is, but you could make it even better. The fact that the game is free is bezarre! I really appreciate people like you who make these types of games and I am honestly grateful that you take your time to listen to suggestions. Best of luck!
One of my favorite Youtubers played it and he likes it too, but all this is my opinions. Thanks
