Thank you for playing and the kind words!
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.
There will be control rebinding so you can change the key, and also have a few different modes for how the grenade works like automatically launching when you release the key.
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.
More variety with the weapons is planned. I think you should be able to finish a mission with any of the weapons, no matter how weak.
3. Make it so items show up in radar even when out of range (by yellow arrow). And perhaps make it indestructible..
Noted. Ammunition will remain destructible though.
