A nice little game! Was playing random games and this one caught my eye. I have some notes:
- The game doesn't seem to fit my monitor size. Anything below "Help" on the main menu is cut off.
- When going to the "Help" section, I have to use alt + F4 to re-open the game because the options to go back are also cut off. Maybe add ESC as an alternative method.
- Some enemies seemed invisible? I wasn't sure if it's something that happens when charging the trumpet, or do you take damage if you hold a charge for too long?
Good job for a first release though! :)
