Hi, thank you for the game, this is a great game.
I know this is still just a demo, but I have some suggestion, if you don't mind:
1. Changing the Grenade launcher to middle mouse button. X is rather awkward position in intense situation. And it's even better if you hold the button to aim the grenade and release to launch. For thermal/smoke, how long you press the grenade button determine how spread out the thermal/smoke is.
2. Weapons variety is pretty much non-existent other than for autocannon, railgun, smartgun. The rest is basically just the inferior version of autocannon (and smartgun is just autocannon with aimbot). I beat the entire game with just autocannon btw.
3. Make it so items show up in radar even when out of range (by yellow arrow). And perhaps make it indestructible..
