Some much needed fixes

After some time, I decided to update the game to fix bad performance, balance gameplay and to also publish a Linux binary.

Some of the changes include:

• Better performance.
• Difficulty was changed.
• Waves changed to 9.
• A pause feature.

But that's not it, the game will also have a bigger update in the future! I have rewritten 50% of the code, while also adding more features.

I've been posting my progress in my Discord server, there I post sneak peaks, executables and also the game's source code.
