Normally I find these types of games exasperating, but this one is a bit interesting in that I can't use click automation. I've seen the "mouse movement idle game" scheme before, but infrequently. So, that's nice.
Also, it's cool to see the improvements between the previous idle game and this, and eventually moving on to "Lost Keys," which gave me a proper chuckle (I also found it imaginative and original.) I'm interested to see what comes in the future.
Anyway, some feedback: it doesn't make sense to be able to buy more than one auto-upgrader--and maybe buyers too, I didn't check--rather than simply having them capped at a single upgrade. The game also loses its appeal rather quickly; I am of the particular opinion that idle games are like the world's worst slot machines, so I view the fact that it loses appeal quickly as a good thing. It caused me to nearly double my original rating, lol.
