You're right to be cautious, thanks for bringing it up. What you're seeing is the standard Windows "Unknown Publisher" warning. This appears for a lot of jam games because the app isn't signed with an expensive security certificate, which isn't feasible for a free project.

The game runs on the love2D engine, a popular and trustworthy framework for 2D games. It isn't a virus. Itch.io also scans all uploads for malware.

I completely understand if you'd prefer not to run it, but if you're comfortable, you can get past the warning by clicking "More info" and then "Run anyway."

Sorry it took so long, but here is one of my solutions. I really need to rework the scoring and requirements by testing a lot more. I didn't mean to make it so hard!

I didn't explain it anywhere, but currently, the scoring is based on how many times cars pass through their own nodes. So if cars slow down a lot because of merging with other busy roads or taking sharp turns, it adds up, reducing the score significantly. Avoiding sharp 90-degree turns is a lot easier said than done, especially with the current ramp mechanics and limited space.

Definitely not a perfect system, but I feel like it worked given the time constraints. I really tried to limit the scope of the game, and even though I had many other ideas, I stuck to my initial plan as long as it worked in practice.

Thanks again for sharing your experience with the game, really appreciate it!

Yeah, I personally prefer using the space-bar to the mouse wheel. You can also press the mouse wheel button instead of scrolling if you still want mouse controls. If you can't remember the controls they are in the help pop-up (top right in-game) or in the main menu.

I thought not showing the direction added to the puzzle and planning, but enough people have suggested adding direction indicators that I'll add it. An easy trick to remember is to keep the loops all flowing clockwise.

Thanks for the feedback!

I understand your point about the ramps, but I don't agree it's the best solution for the game I'm making. I like how ramps take up road space and prevent bridges from having a direct path. It's a decent idea, and I had a similar thought myself, so I might experiment with it after the jam. I am worried it will change the game too much, though it might be for the better.

My idea was that not showing the direction would be a good challenge, forcing players to plan their solution ahead of time. For example, if you just make sure all the loops go clockwise, it's easy to keep track. After the jam, I'll have to add something to help people remember the directions, and also add an indicator for bad paths that don't link to anything.

Thank you for the feedback, I really appreciate it!

Right click or right click drag to delete paths of the type currently selected. There is a help section in the main menu, and in the top right of the levels there is a help icon for easy access to the same information,  so you don't have to go all the way back to the main menu if you forget something.

I wanted to give the players more control when deleting things, that's why it only deletes the same type. I'm already thinking of different ideas to solve this issue, and I'll probably implement most of them like a toggle to enter a delete mode where you can clear anything like in the level builder, and maybe people would find an undo button more intuitive. 

Don't worry, you're not the only one who got confused by that! I got too focused on clearing clutter (you can tell if you look at the settings) that I hid the controls in the help section which nobody actually reads. I think I need  to come up with an interactive tutorial after the game jam, as well as implement the other ideas.

The placing sound was made using standard cards and some audacity effects, very happy with that sound.

Thank you for playing!
