From the start the game menu felt nice and polished. Great music. Reminded me of Dreamcast-era Sega: super energetic and exciting.
Dialogue test looked good.
First time playing, the opening level was surprisingly challenging. Took me just under 5 mins to complete. I’d suggest having a few shorter levels to introduce each mechanic (basic movement, jumps, combat, etc.) then have your current opener as a test putting it all together.
Played on macOS, game ran well and didn’t experience the shrinking ball glitch.
