I'm not sure where to start..
You should fix the download first. Since right now you download a z_data.rar which you have to extract in the same folder you put the exe.. Why not just put the z_data folder and the exe in the same folder and then just have players extract that instead of making it more complicated?
You have a bunch of robots with parts you can combine.. and there's even a rating system that shows you some parts are worse than others..? I almost got deaf from the loud random meows and noises at the beginning of the game and had to manually turn down the volume of the application since there is no option for that ingame. I played with the red robot since he had the most attack and beat the game. I'm not sure what's the idea of the combat is.. All i did was turn on the speedhack of cheat engine so i could speed it up since all you can do is watch. The game ended.. skipped more dialogue, and the game restarted, i believe?.
But if the idea of your game was to mix a dress-up robot themed game with a little visual novel, in that case the game would be okay. and the art is nice.
