Hi there!
I feel really sorry about that ice block bug. : (
I imagine how it could be frustrating and spoil the fun.
Indeed, I didn't have time to implement the coming of Marisa and Sakuya, but there is a win condition at XXXXX xp (canceled bullets).
There is a determined sequence of different patterns, then randomized patterns.
Indeed, I need a better balance, I'm working on post-compo version.
Thanks for playing. : )
Take care!
