Just updated a new version where I fixed some minor bugs and made the Arena mode better. I also updated to Godot version 4.3, which means that there's no longer crackling audio.
Updates and bugfixes:
- Last level's boss fight is more fluent
- Stamina bar won't get stuck while using ninja rope
- Random monster spawning in Arena
- Quit game (esc) works now in every level and in Arena as well
Here's a gameplay video:
(EDIT: Changed gameplay video to 4.3 version, the audio is sooooo smooth!)
