I had fun playing this! I really liked the art style, and it didn't take long to figure things out. It took me a few seconds to realize where the charge station was, but after that it all clicked.
I noticed a couple of small UI things. The last message at the end appeared underneath the "Hello hello" text, and I think the dialogue would be a bit easier to read if it wrapped whole words instead of splitting them across lines. For example, keeping words like "system" together.
Overall, great game! I enjoyed it.
