Updates/v0.1.9 released

September 24, 2026

This is the third development preview released on September 2026. This release builds on the release back in June with additional types of rooms, decorations and customizations, a huge slew of optimization and backend rework, achievements, a market demand system, and mod support.

This release introduces the following new features:

Rooms

New rooms

• Stadium - Brings even more visitors to your tower
• Garbage Room - A small staging area for garbage generated by tenants. Rather than having them carry garbage all the way to the Garbage Dock, they can now store them in a nearby Garbage Room to be emptied by Housekeeping or Loading Dock workers.
• Delivery Bay - Delivery bay accepts mail and deliveries for your tower. It is a larger version of the Loading Dock which can be built underground.
• Decor items - A bunch of new decorative items have been added. You can adjust the colors for these items.
• Apartments - Similar to Condos, but these are rent-only.
• Restaurant - Provides food for evening and night time

Updated rooms

• Added additional variations for Fast Food Restaurants, offices, and stores.
• Certain rooms can now be upgraded for additional capacity including Mail Rooms, Power Distribution Rooms
• Vending Machines are now used by people passing by.
• Parking Ramps are now placed on the ground floor first. Car access is provided by connecting to a parking ramp. Delivery Dock, Garbage Dock, and Parking Stalls all require car access by being placed adjacent to an existing parking ramp.

Maps

• Added a new Tokyo map.
• Updated Tutorial map with a more complete tutorial.

Game mechanics

• Reworked room requirements system. As your tower grows, rooms may start requesting additional services to be provided. The score based evaluation system from v0.1.6 is now extended into a percentage system which should be more intuitive.
• Projects and secondary objectives. You can apply for a small grant when accepting a project. This should help with mid-game progression with additional guidance and capital.
• Market demand and visitor calculation system. Offices previously randomly become rented independently. With this new market demand system, your tower growth is dependent on the needs of a wider market system. Visitors to your tower is also governed by this new system: More varieties of attractions and buildings attracts more visitors. Special events such as bad weather reduce visitors.
• Room levels have been removed -- instead, room's demands now match your tower rating.
• Loan limits are now dependent on a few factors: Your tower's net worth, your tower's yearly net income, and the starting funds + game difficulty.
• Game difficulty can be adjusted which changes market demand and tenant evaluation scoring.
• Hotel rooms now age and require renovation to keep its attractiveness.

Mod support

• Adding Steam workshop support. It should be relatively easy to add new rooms and decorations. Future support for custom transports and sim types and variations may be possible.

There is still work to be done with focus on additional maps, game balancing, optimization and performance, and overall polish. I hope you’ll have as much fun playing this preview as I did working on it.
