It's okay but shouldn't be segmented into episodes
It was reasonable but you need to remove the bugs, especially as it's so short and 'nothing really happens', as it were, you need to make certain it's nearly perfectly coded to get good marks.
Other than that, I appreciate that probably the next parts have not been built and you want to publish what you've done straight away because it's exciting and you want to get it out there, but there isn't enough content here for this episode to stand alone. You're better off publishing all of it in one larger game, and I think players will take more kindly too it too.
It's something I can see you can build on, so I'm not being overly harsh on my scoring, but if I was rating this as a stand alone game, it would only be getting around a 3 - 4. Go through the code, get rid of the bugs, get the second and third parts. or however many you're doing, and publish all of it as one thing, not in tiny segments, and then you'll have a much better game.
