If you're not too far into the project I'd love if you built it on Orbem Studio. Top down pixel art games like this are perfect for Orbem Studio which is a free no-code web game engine that had live collaboration building with built in chat feature. There's also a built in art tool for pixel artists to draw/animate/edit game assets directly in the game. You get a free hosted URL you can use for building/playing/testing and when your done you can even export the game for monetization on itch.io or steam.
I'd be more than happy to offer full technical support and feature requests as you build out the game. If it's already too late definitely consider Orbem Studio for any future projects. You can check it out at orbem.studio
Good luck with your game either way!
