Enemies are much more durable than I am, it gets unfair really quickly when a couple spawns next to each other.
And grenade can't really hit air.
Thanks! You're right about those points. I don't want the enemies to die too quickly but they are much more deadly than they're supposed to be. I'll make their shots easier to dodge and lower the spawn rate and max spawned enemies.
I've increased the grenade hitbox size to make it easier to direct hit stuff and I'll add a second weapon slot so you can have a backup for tricky enemies.
