Thank you so much! About the issues you mentioned, I completely agree. Most of the gameplay was implemented in the last 30 minutes, so I didn’t really have time to properly playtest and polish everything.
About the controls, the arrow keys and E were there from the beginning. WASD definitely would have made more sense. I just didn’t get around to changing it before submission.
The game ends after 240 seconds, or 4 minutes, and the idea was that if the bills stay above your current balance for too long, the lights shut off. That was the intended design, but I agree it could have been communicated much more clearly.
As for the theme, I was going for an internet café, like the computer clubs that were common before home internet became widespread, rather than a traditional coffee shop. That said, the café aspect definitely could have been shown more clearly visually.
I’m really glad you enjoyed the core idea, even if the execution could have been better. Thanks again for the feedback. I really appreciate it, and I will work on improving those issues soon! :D
