First alpha version and discussion

This is my first project that I put on the Internet. Please do not judge rigorously, but advise that I do not correct.

I chose Unreal Engine for this game because it has more features than Unity and in my opinion, it is much simpler. But there was one problem. I can't learn how to create level prototypes with the built-in feature in Unreal. It does not have the one opportunity I need. This problem is solved when you buy an asset for Unreal. You can look at this link. But unfortunately I don't have the money right now to buy it. Please help as much as you can. Thank you very much!

I started to do  this project with a video course from gamedev.tv. I was interested in this project and I continued to implement it. I still have a lot of ideas that I want to add to this project, but for the moment, please tell me how physics works or if there are any problems and what ideas you can add to this game. If you have the opportunity, make me a company. Unfortunately, I cannot be for everyone: for the designer, for the programmer, etc. I don't know how to draw or create models very well. I can create the best programming logic for the game. I would greatly appreciate it if anyone would like to join my project!

If you want help translate this game, then follow this link. if you would like to add another language to translate, please follow this link again. I will be very grateful!

Thank you all for your attention!
