The game is quite fun, the idle mechanics work well, and the retro art is very pleasing.
For me, the text under the shader is a little difficult to read. But maybe it's an issue with my monitor. A full-screen button would help a lot (it's an option on itch.io, if you want to add it in the future).
The progression is natural and fun; however, at some point, the game becomes almost completely idle, as it takes a long time to get upgrades, and with the automatic collector, there's not much you can do. A trick that idle games usually use for this is to add some mechanic that depends on constant user interaction, for example, clicking on the screen to earn coins.
But I'm being nitpicky, you did a good job, congratulations on your entry!
PS: I read some of your logs, it's very fun to follow your creative/technical process.
