OviLex

OviLex Software Productions, trading as OviLex, is a Romanian software company based in Cluj-Napoca that develops and sells mobile gaming apps on Android OS, iOS and other platforms. It specializes in free-to-play simulation games such as the popular Driving School car driving simulator and its subsidiaries, Euro Truck Simulator and Coach Bus Simulator. Founded in November 2011 by software developer Alexandru Marusac, the company has a combined over 100 million downloads across all its games. The company also makes other IT software.

While many OviLex games are highly successful in terms of downloads, many customer reviews (most notably in Coach Bus Simulator) have experienced many technical bugs in the game's programming, for example an issue with the bus shooting into the sky when the player collides with in-game obstacles, physics engine malfunctioning, unintentional turbo mode and infinite fuel, and the game constantly crashing. OviLex has released bug fixes (also known as patches) to several of the games shortly after their release, but only continues development support on its most popular games (in this case Driving School), whilst Coach Bus Simulator support has long ended.
