If you do decide to play my game (which I would appreciate, but don't feel obliged) then feel free to play the WebGL version here to save you having to download files: https://moocow17.itch.io/rewind-bullethell-web-version
It is exactly the same as the official submission for the game jam, bugs and all, I just ran out of time uploading the WebGL version during the jam, so made the WebGL version afterwards. Obviously you can only rate the actual submission (https://moocow17.itch.io/rewind-bullethell ) though.
