Now that Demo 1 has released, I can finally work on the rest of the features instead of worrying about fixing ones that are already there. Some expected features in Demo 2 are:

SHOP SYSTEM

A shop system is planned to be implemented and put into Demo 2 and so forth. The shop will appear every 5 waves and you can buy health kits to heal yourself fully, extended magazines, and a cooldown lower.

ITEMS

Items are expected in THIS update but will be further on. They would be bullets, small temporary power and health upgrades, and bandages to heal yourself a little bit.

The rest of the features will come in Demo 3 and so on.
