Such a good schmup game!! I like the menu and the variety of options.
The way you implemented chain reactions was neat. The small eggs made it easy to understand, but it would have been cool if the larger enemies had bigger chain reactions, like shooting a ghost bullet in other directions.
The artwork is clean. Visually, things are easy to see and follow. The menu placements are good and remind me of Touhou.
I'm happy that you added an infinite lives option. I really wanted to see the ending, and was happy to be able to beat Mint! Great and fun game!
