Hello! One of the improvements on my TODO list for the next update is to give the game a quick help menu that can be pulled up with the F1 key (from what I've heard, this the default help key). Reason for this, is that there is actually a system for firing with the mouse, its just a little wonky.
The current system I have in place is that the left mouse button fires only your selected groups. Groups can be selected by left clicking on the appropriate groups down at the bottom of the screen. Selected groups will show all of the weapons in that specific group. The fire all key used to be ~, but that has since been changed to the right mouse button. The reason for the weapon selection is that I wanted to give players the option to fire their core weapons (the ones that primarily deal damage) without having to fire everything. That way you can have all your core weapons in a single group, select it in battle, and only fire those without having to fire your flares or wind weapons at the same time.
I think the main problem with this system is that it takes a lot of work to go and select groups to fire since they are already fixable with the key binds.
That being said, if nobody knows about the controls, it probably means that the controls are not intuitive enough. I have plans to make a weapon group visualise tab in the editor(like the shop or forge tabs, but to toggle settings like autofire/selection before the battle). Eventually(not sure when, hopefully soon) I will get around to implementing editable hotkeys, which is great. but still won't solve all of these problems.
I would love to hear more of your feedback in the discord, especially on your suggestions for the firing system!
Thank you so much for your feedback! I really appreciate comments like this.
