Thank you for being so positive despite that, lol. Here's a few tips based on things I noticed during play testing (If you're someone else reading this and haven't played the game yet, I think it's more fun if you go in blind!):
-It's better to use one tool on all four parts at once, as opposed to using every tool before moving on to the next part. That way, it's easier to notice a difference in readings since the image of what it's "supposed" to look like is fresh in your mind.
-Sometimes the alien can trick a tool, so if the readings look the same across all four parts, they probably are! That just means you need to try a different tool.
-The acoustic tool (the iPod) needs to be used in several locations along the length of the part to catch any weird spots. It helps to spam it as you're moving it up or down the part.
I hope this call into the Cosmonaut tipline has been helpful. But regardless, thank you for checking out my game!
