Well Just use the arrow keys. It won't be perfect but you can still check it out. It is in beta though.
3/25/21 kinda released just sharing it even though its in progress. I just felt bad so I wanted to make a game. I hope you like it when its done. Also I am a little new so if anybody could share a link in the comments how to make a smooth jump and fall that would be awesome. And If somebody does that I will give you credit for helping me a ton. :D have a great day enjoy the beta version for now. also it is not released but once I find out how to make a smooth jump it will be a lot closer to being finished. So If you can comment if you know how to make a smooth jump and fall show me. "I will give a huge credit to anybody who does it! Well see ya! Hope you like the beta version.
