Good try! I imagine the limitations are due to a lack of time or current knowledge of the engine. The concept of using previous one's deaths and persistent states in order to eventually overcome puzzles and traps is a good idea, but would've liked to see more use of that mechanic, like leaving bodies behind to mark the deaths, some way of making the deaths more impactful rather than seeming like just a teleport, spawning a dead body, blood splatter, sound and so on. I think we needed more levels with various traps to explore the concept a bit more.
It's a simple but functional game, you made all your own assets so I imagine a fair bit went into the minecraft esque indiana jones character and figuring out all the triggers for traps. Having sound effects would have gone a long way into making the game more fun to play. I think a few people have trouble with the menu because you don't click on the buttons but use the navigation keys, it caught me out the first time.
Good job on the game!
