Your branding is absolutely consistent - from your channel art, thumbnails, avatar and carrying it over to your videos themselves. Fantastic work!
Biggest issue for your channel at the moment is your microphone setup and there's a minor issue with the edits in some of your videos (mostly list videos). In your voice overs, I can hear a lot of plosives coming through your mic which tells me you either haven't got a pop filter or have the mic way too close to your face which negates the pop filter entirely. Invest in a pop filter for the microphone you use for your voice overs or keep the mic further away from your mouth.
For your videos where you have multiple people playing, you should consider investing in a mixer and 4 seperate microphones to capture audio equally. At the moment from what I can hear, 2 people are coming in relatively clear while the other 2 are incredibly soft. With 4 seperate microphones and a mixer, you can increase the gain for those who speak softly while lowering the gain for those who speak loudly, ensuring a consistent, level volume. This suggestion is entirely dependent on your budget.
As for the edits, the long periods of silence between sentences (most prominent in your "Our 10 Favourite Generation One Pokemon") has to go. I get that it's easier to record things line by line (most people do) but edit the audio in a way that it sounds natural. Have sentences flowing from one to the other. At the moment you have extremely long pauses between sentences which is not natural at all and makes the video boring to listen to.
Overall though you're definitely doing well. Work on the issues I've mentioned and your channel will grow.

Starting from your first video, your english is very good, you're using a lavalier/lapel microphone which is fantastic and the video is recorded in a high frame rate. Absolutely great start!
The videos have increased in quality as time has gone on in terms of lighting and editing. To be honest there really isn't anything I can advise you on for your videos. You and your boyfriend know exactly what to do and your channel is already seeing tremendous success after 3 months. Keep it up!

The font/typeface you're using and the gradient you've treated it with is consistent across your channel header and thumbnails but not your avatar. Your thumbnails have definitely improved as time as gone on which is great to see.
Videos are well edited although your vocal audio is way to loud and of a low quality. You're using a headset microphone which is convenient but I suggest saving up and investing in a condenser microphone with a pop filter.
Audio is definitely holding your channel back. Clean up the quality of your voice overs and you should see some improvement with subscribers and view counts. Good luck!
