Was a superfun experience! Completely annihilated everything with this build, didn't seem to use any magical spells I think. The combination of the genre's did feel that they matched well with each other!
It was nice to see the boss beforehand and get a feeling of what is to come, but as mentioned in some comments, it ended up being a bit underwhelming. I guess the nature of the "left/right" tower defence does limit the options.... Perhaps the boss could mess around with one of the items in my equipment?
if it helps, for all my Godot submissions I tick these boxes on itch, and it does help with the fullscreen

My game screen stopped playing at the end, this is the "chest softlock" I see GameFavorites mentioned perhaps.
