The game feels a little incomplete without any animation to the action. I would recommend adding a simple animation for lifting and then perhaps some tweening of a +1 gui to indicate a new point in the strength. These can help give the game a little more life!
The game definitely appeals to me at start, but when I joined and took a look, not so much. The User Interfaces seem quite plain, the map is extremely small, there are no animations, it has no thumbnail, no backround music, and worst of all, it leads you to another game before joining your game. Let me tell you, there is no “Faster Roblox Loading” by joining another game first. It actually slows down the process. If you fix all these problems, you may have a working game.
To be honest this game seems very similar to the popular weight lifting simulator. With this being said, some things from the weight lifting simulator can be used for ideas and references.
This happens a lot when creating games, games are usually based on an idea or another game. Looking at another game or playing it can help give you ideas or references.
Currently, the issue from my perspective seems to be the similarity between weight lifting simulator to this one. This means you are going to be competing for over each other, so you should ask yourself why players should be playing your game over another. Is your game better? Does it have more features? Is it engaging?
When making games similar to another that already exists you should be prepared for the worst where you can not compete with the competition.
Also, it seems like what needs to be said has already been said above in terms of game content.
