To" jump" press either W, Spacebar or Up Arrow! To "duck" press either S or Down Arrow! Basically in this game you need to do the same thing from the Original game of Offline Dinosaur! (Jump, duck, crawl, etc.) There will be a tutorial in the game for further information!
I used ideas from the Original game of Offline Dinosaur, but it's fan made, by me! There will be a lot more stuff in the future, but at the moment it's just the default game! Of course, if you choose to, you can recommend things for me to add in the comments! I am welcome to all suggestions! <3
