Feedback on my Application

Good day everyone. I just released Alpha version of my application/game.

Before you start testing,

This game is already created by few developers.
This game is created to test how much parts that your device can handle.
You can explode parts.
And there is a house explodes in every 1 minute.

I want your feedback.
This game is still in alpha, there can be bugs.

I feel that the game is pretty good, only thing I would suggest is that instead of when your character spawns, load in the GUI, when the player is added, load in your GUI.
