World XII is brutal damn. Barely managed to unlock world XIII and cleared its first level. Only glanced at the remaining ones and I'm already pleased with what I see, looking forward to attempt them later.
Lockmess monster still baffles me and I feel I'll be pretty mad once I realize what I'm missing.
Great to see quick updates, I'll have to revisit Moonbud and Frigid Engine then.
A couple more optimizations for good measure.
