Hello everyone!
I am glad to announce that Shipolis is part of the Prismatic Indie Showcase that is happening right now! Also, I recently released a couple of patches with some improvements and fixes for the demo, you will find the full changelogs below. I hope this event will be a good opportunity to discover the demo, or return to it, or spread the word, or simply enjoy the other games included in the showcase.
I wish you all a great event, and I'll see you next time!

Changelog Demo v0.5d:
Tweaked the visuals of the upgrade tree to make things clearer and better organized
Changed Bank / Temple / Clearing turbine / Shady park so that they can be built only once per city
(Deck/Controllers only) Opening a city menu now focuses directly the first building tile of the city instead of the cancel button
Fixed locate button of a route not working when just deleted another route
Fixed game menu opening lagging when many routes
Changelog Demo v0.5c:
Added current wonders progression on the right side of the HUD (begins to show when you get the ability to start a wonder). Added an option to hide it in the Interface settings
Added more ambient sounds when placing buildings
Improved the info cards in the list of current routes in the Routes tab. Added locate buttons to highlight cities or the current ship location on the map. Added a glowing background to indicate the current step of the route. When the route is idle, added display of the reason why. Changed route tooltips when hovering on the map to use this same info card. Hovering the route on the map scrolls the list to the corresponding info card.
Tweaked the coins sprites and renamed them to avoid using material names that could be confusing
Ship markers on the map now reflect the true sail color and flip to correspond to the current ship movement direction
Tweaked the camera to be smoother when moving/stopping in quick successions
Modified the gamesave cards to better indicate the current progress with regards to the end objectives of the game
The mini floorplan in the city tooltips now reflect the wonder progression
Added a flag in the empty tile icon of cities to clarify which one is the main coastal tile

Fixed some tooltips being slightly off the screen when hovering on the minimap in the top right corner
Fixed ambient sounds not properly fading in/out while in menus
