I've reached the second fight against the (first?) boss once so far.
The game is very fun. There are plenty of cool bullet patterns to deal with (these bullets from the second phase of the first fight against the boss are super cool), the difficulty feels right (or at least up to where I managed to get ;) ), and the theme mechanics is very unique and interesting to deal with, there are parts I am familiar with now where I'm not sure where I like to place the light the best, which is cool.
Very cool entry, thanks for sharing.
