Thank you for playing it again and your kind words!
railgun ammo is very scarce, and considering that it takes a while to charge it to pierce through buildings decently, it honestly does not feel reliable enough for a primary weapon during a mission long term. it's so powerful that it almost feels like a secondary weapon to deal with powerful enemies, not something you would use against tons of minions and weaker enemies.
That's completely fair, I felt by limiting the ammo it would be a way to balance it since it's basically a 1-hit kill weapon, but without a secondary primary weapon it's probably not going to work.
it also happens VERY often that i mistakenly press LMB not long enough, and waste a cartridge with nothing to show for it.
You only need to hold it for about a third of a second to not waste a cartridge, the timer for it is actually just about ~10 frames in game. The cartridge dumping is kind of just to prevent players from mashing LMB and encourage them to wait and line up their shots more, but I realize an indicator for when its ready aside from the maximum would be nice. Sorry about that.
the grenade is kind of situational. i can see it being useful in some circumstances, but most of the time i would rather just destroy the obstacle between me and the target with whatever machine gun i currently have equipped rather than having to press x, press it again and then wait for the grenade to finish its arc and reach the target
I realize I kind of need a tutorial and maybe a non-lethal grenade for this, but you can use it to bait enemies with explosions and also hit them when it's at a really convenient time. As you said, it's situational and I think it's best used when enemies are near explosive containers or way behind dozens of buildings since it can hit them from anywhere. Eventually I'll have different types like EMPs and smoke grenades so hopefully it'll be more useful then.
the scatter gun felt pretty wimpy. the scatter itself is pretty small, and by having to wait between each shot it feels like another inferior alternative to the machine guns, and the increased damage does not make up for it.
Gotcha. It's best for wiping out groups/formations of enemies like in the fourth and second level, but I can see why it's not as useful as the MGs. I'll see if I can improve it.
Thanks again!
