A Touch of Spring

Hello everyone,

Spring is almost here — and Summer Islands is getting warmer too. We’ve been working on the next update for a while, and now it’s finally time. We’re happy to present v1.0.3, featuring:

More seasonal vibes (toggleable) Look forward to cherry blossoms in spring, maple leaves in autumn, and snowflakes in winter.

New special Japanese building A true highlight: a unique Japanese building that tourists will absolutely love.

Dynamic news banner News is now more dynamic, clearer, and easier to read — so you can quickly see what matters without constantly clicking around.

32:9 screen support Ultrawide fans, rejoice: 32:9 support is here — for more overview and more island.

Buy enemies Yes, you read that right: you can now buy enemies — a new option to spice up your strategies.

Yearly report opens automatically at year’s end (toggleable) The yearly report now opens automatically at the end of the year, so you won’t miss your progress.

Accessibility options More accessibility for everyone: high contrast, bigger cursor, outlined text — so Summer Islands feels good for everyone.

Performance improvements & engine update We’ve done a lot under the hood: engine update, optimizations, and noticeable performance improvements.

Improved umlauts (ÄÜÖ) Small but important: umlauts now look better and display more reliably.

Bugfixes, bugfixes, bugfixes And of course: a whole bunch of fixes — many small annoying issues are gone. (But don’t worry… we’ll keep sneaking in new ones so you have something to hunt for )

Thank you for being part of Summer Islands! Thanks to every single one of you for your patience — and now have fun with Summer Islands!!

P.S.: If you’re enjoying Summer Islands, please, please, please leave us a positive review! A small or means the world to us!

Your Summer Islands Team — where vacation never ends.
