Thank you so much for playing!
I was doing illustrations before diving into gamedev, and this is my biggest project yet. You are definitely as capable or even more capable than me, I really love your character portrait for your first 3D entry for the jam (that quake-like/ultrakill-like one), and also the cover art for your jam entry is really amazing!
About the spider sprites, I kid you not they are made 1 hour before the deadline xD Before that, they just godot icon.svg floating around (including the boss)
Godot 4.5 stable is not released yet, but the upstream / dev version is already there ( https://godotengine.org/download/archive/4.5-dev5/ ). It really has some nice features with new useful signals such as get_tree().scene_changed (great for transition). I just stripped down its features, so the export size does not reach 30 MB.
Anyway, thank you for playing and for the feedback!
