wow, for your first ever game, this looks really good! love the intro sequence and everything, your sense of presentation and delivery is really good! the pixel art and text gives it a nice sense of style while mimicking the look of these old computer start-up screens from back then! the audio sells it too, with each sound effect being nice to listen to! the lo-fi song was also a nice little addition to put in the background while im just clicking away xd.
i'll echo the same sentiments from the comments and say that i wish there was more upgrades to buy, even if it was just infinitely incrementing xd. though this is something that could easily be added if you wanted to, so its not a big deal!
again, really impressive that this was the first game you made, looks really nice! i can't really say the same for my first game xd. hope you had fun with the development process! great work!
