There is some positive in the game: the graphism and atmosphere is pretty good, the tutorial written on the floor and wall is is easy on the eye and effective (for the most part) and the setting has undeniably potential.
Unfortunatly I've had a frustrating experience because of the level design of the game... You mentioned in other comments that a lot of people die in front of the first mummy; that's because when you introduce the click to take item, the player has to move toward what seems to be the only thing they can interact with and click. So when you tell the player to press a new button right after, they are gonna do the same (get close to the sarcophagus) and then press E, only to get mauled to death instantly '~'
Also, towards the end with spiked pit, I fell for quite a stupid reason (me really). Considering what revealed the way was an eye, I considered that the way to the last artifact was merely invisible but still here, and that I could keep going without alarming the mummies much. At the bottom of the pit, I realized I was wrong. I didn't feel like doing the game again from the start so I stopped there...
All in all, I've probably had the worst possible experience I could have had with this game, no luck ^^' But aside from these two mishaps, which I'm way too salty about to be honest, that was a great work! Keep working on it and I'm sure it will turn out to be a very good game :)
