A very nice game, enjoyed playing it, didn't see any issues (just some enemies getting stuck but it's not that big of a deal)
It is so satisfying when a ton of enemies is chasing you and you just kill all of them.
Though i have been playing it for some time I haven't found a single artifact?
I would rate it 6 stars for gameplay because of Ricardo, but the thing is... it doesn't have a highscore function, which was the essential restriction ://
But other than that this game is quite fun :D
