Amazing presentation !
The game looks awesome and is very well animated, the launch sequence followed by the title scroll really feels like some authentic arcade style game, i also like that you leaned on this aspect in the menu as well with the ship selection screen showcasing the shot's patterns like it was in classic titles, i really enjoyed the ship designs as well, and the parallax on the clouds look awesome.
Gameplay wise the controls feel solid and responsive, but the difficulty was a bit too insane for me, these bullet speeds are fast !
I managed to survive up to the first boss but didn't last much longer fighting him, still had a fun time though, and the game has a lot of polish already for a jam entry.
Good job :)
