The most annoying thing were how far away 5 and 6 are from WASD.
A different playtester suggested using a modifier key, like CTRL, to access the bottom row of chemicals. For instance, you'd press 2 to add one fire and CTRL+2 to add one ice. What do you think of that idea?
And I didn't know where to put the weapon switch key. Let me change weapons with the scroll wheel and I will use the scythe, ty.
Heard this from other people as well so I'll add it. I've always hated accidentally bumping mouse scroll and switching weapon in other games so I never added the binding haha. You mentioned that there's no incentive to use the scythe in the stream but there actually is one: damage. If memory serves me right, the scythe deals ~80 damage to an electric Watcher with a 4x fire swing. You're basically trading the safety of range for high burst damage.
Another thing is, I usually just went for full charges and just mashed the number keys. But often I wasn't sure of if I hit it 3 or 4 times. For these reasons, I personally would prefer if there were 3 charges, or even 2, that would make it feel less annoying input wise for me.
What about instantly filling up with a chemical if you hold its key down for a bit? I don't want to reduce the maximum number of charges since that would reduce the amount of combinations you can make by a large factor.
I would have liked a sort of training room with dummies or something to test stuff out. I like to experiment with mechanics normally, but I don't feel like you have too much room to try out stuff while you're fighting against dudes in the wild.
A tutorial that includes this is a high priority and should be in the next update.
Thanks for playing and for the stream! I'm surprised you almost beat a run without knowing you can heal yourself with your utility.
