Hey congratulations on your entry. I like the theme of this submission.
The difficulty curve feels a bit unbalanced or maybe its just for a more experienced player than I.
I can understand you feeling like that as I didn't really consider the balance too much. I knew it started out pretty tough and the final boss is perhaps too easy compared. I'll keep that in mind in any future shmups I create, I'll try and get more of a flow and curve down - thanks for the constructive feedback, very much appreciated!
