Take a few minutes and google 'how to record a game' also. Use Bandicam (with that watermark) or preferably Open Broadcast Studio (which can do recording and streaming functions).
You want the game to be playable in full-screen borderless windowed mode. If that can't happen and you can't google the RPG Maker scripts to make it work then you will lose some of your audience.
You also want someone to playtest the game. Preferably a friend/family who has some free time. You should be playing other games and learning from them and copying their methods.
Your visuals aren't doing you any favors. Consider getting doing a google search for some non-default asset packs and start replacing the default artwork.
Do some YouTube searches for 'RPG Maker Map Design 101' and take that to heart. If you expect your players to go through yet another dungeon then there better be an interesting map to go through.
If your random encounter rate triggers a random encounter more than once every 30 seconds then you will lose a significant portion of your audience. We are NOT still in the 1980s anymore and we have so many options for entertainment that this game is a mere tiny blip in the vast ocean of games.
You wanna make games for a living? Start showing some initiative and I hope to see an improved version of this over the next year or so.
Good luck.
