Time has not been kind to this point and click flash game experiment. I'm not sure if it's just the quality of the game or errors caused by how old the game is, but expect to run into issues and bugs if you give this old game a second look. If you do get it working and get through it, unfortunately you will find it's not really worth the effort.
but part 2 is better than this one
I'm a big fan of Murder Mystery games so I was disappointed that this was so easy. There are only like 5 things to see!
Needs an overhaul
You started with a cute idea, but made a game that was far too simple. I don't think I even played the game for 5 minutes before solving it. Also please, never make up fictitious blood types for a murder mystery game.
