I think, the force transfer to the other site shouldn't happen. That said, they should disable that force site load (and probably force scaling, if it's added up to the site part).
Why isn't the main character animated like the froggies? Two or three frames for each direction would suffice.
Also, not sure what shield points are designed for. They don't seem to save from froggies' hits. Haven't tried taking bosses' and medusas' hits.
Also, after the BGM was turned on, the game decided it didn't want to load again (perhaps it was just taking longer essentially, but then it was kind of too long).
The gameplay and the visuals are nice.
Needs polishing before becoming a non-demo.
