It's possible that I forgot to scale some of the UI, but good that it fixed itself on relaunch. I'll definitely add a skip cutscene option.
I'd agree, the final boss is definitely too hard. I think it was a case where the game was getting too easy for me, so I decided to throw a curve ball in that felt challenging to even me.
The idea with the electric field attack for the final boss is that the player can use the shield to cross between the edges to move away from the boss. Quite a few people have expressed frustration with this since I don't think it's super clear. You want to walk through the field away from the boss to get some space. You're probably right, the electric field does go on for too long.
Thanks for the review!
