Archeopteryx 2 (Arx2 for short) is my own game engine.
It uses the DirectX libraries and their C# wrapper SlimDX.
Its first version (Archeopteryx) is used for the game Archamon.
The goal of the second version is to create a more stable and powerful engine with fewer hardware requirements and simpler implementation.

AlcoHole is an application for monitoring alcohol consumption. Its primary goal is to motivate users to maximize their consumption. In addition to detailed statistics, it also allows you to monitor the amount of money spent on alcohol and the current estimated blood alcohol level and the time it can drive.
