I’m definitely a big fan of this type of game, the creativity of getting to draw in your own geometry. It’s especially nice using a drawing tablet as an input device (although I had to run it in mouse mode, the pointer mode didn’t register my clicks which is pretty common in applications I think).
The vibe is really chill and it’s got a good amount of visual polish, and I didn’t experience any noticeable bugs. I’m not sure if this method of testing civil engineering infrastructure is approved by OSHA or FHWA/DOT or whatever. The engineer sure puts their life on the line in this one – very trusting of the player’s design.
