At the time of review, basically just has the "Play your own music" system and a settings-matching minigame working. The store delivers errors in boxes. Said errors fall through the floor if touched, and otherwise can't be interacted with.
I don't know if the microphone system actually works, as I only have access to a USB headset for a microphone.
For immediate feedback:
The settings-matching minigame doesn't show if you've successfully matched a signal, or the signal just timed out. If they time out, anyways. It just goes straight back to standby.
For the echo: is it possible to run the same audio playback out of multiple sources?
For the casette player: The power switch needs to be down to actually play the music. Tripped me up for a few seconds, as I thought "on" was up. Apparently power is optional for importing/recording music on to a casette.
For the shop: General UI work is needed. The UI is MASSIVE- too big for the monitor, and I can't tell if I need to interact with the screen or the keyboard.
For a simple suggestion
How about pre-recorded interviews? Something that just gets delivered to play. The voice acting was quite good, and the writing there gave me a good laugh, and it seems like a good, easy-to-implement way to add more of that.
Has the potential to be quite good, but needs a LOT of work. Keep at it
