This has been one of my favorite submissions so far! I have always been addicted to these kind of games of progressively getting more and more multipliers and getting absurd numbers! This was really well done, so thank you for the experience. The art looks good, the music sounds good too, and the descriptions were really fun. The idea of naming the currency "curiosity", given the theme, honestly just made me laugh. It's so great, I love it!
One of the best parts is that you managed to create from this style of games something really interactive. A lot of time these incremenetal games get to a point in which you don't have to do anything, just watch and wait. This is fine obviously, but I appreciate the switch in gameplay. Having to control multiple minigames at the same time was simply genius man! congrats! It gets a little crazy controlling everything, and then I tried to do combos with the difficulty setting and the radioactive thingy which resets all minigames. Simply awesome. It was a really good experience. The ideas that you had were fun, smart and enjoyable.
My only note is that numbers get too high too quickly. They always do in these games, but here already at the fourth door you can see it costs 3.000e4. So you're already leaning to scientific notation! It feels like you don't have enough time to savor those early stages in which you earn almost nothing, and as you slowly build up, but only after a while, numbers start getting absurd. Kind of like in cookie clicker but in a much shorter time frame. I probably would slow the progress down, make the first doors give less curiosity, and let it build up. And also, I would only lean to scientific notation after the billions. Most people can easily recognize up to the millions and tenths of millions, so the build up looks so much better. Only then you go to that famous e.
Amazing game!
