I am not a big fan of the controls, but I see what you were going for, to me they lack some fluidity and it's a weird setup for me, my brain expects left click to move and right click to attack, while having spacebar to dash.
I think this game needs tutorial level, somewhere to get a hold of the controls as a bit of a playground, with an easy boss so that you can get used to the game without going straight to facing the actual bosses. But probably you weren't able to do this due to time constraints.
The bosses are really well designed, both in artstyle, which is really cool what this game has btw, but also in attack patterns, they require precise movement which is why I think you went with the click to move approach instead of WASD, that's a good thing but again, don't know if many players are used to this type of movement, I only somewhat know this because I've played Lost Ark, and even then, I had to look at the description to know how to move.
Love the lore, I just would like a way to skip it for when I load the game again, I see you have a fast scroll option if I hold left click, but I think a proper skip button would help.
Overall good game, very impressive, I saw this game is an entry to four game jams, extremely impressive how you pulled that off. It just needs a way to introduce players to the movement and let them experiment around before facing the bosses and maybe polishing the controls to be more fluid.
