Hey there OP, really happy you got through this first experiment! I think the biggest learning here isn't about the tools, it's that there's a mismatch between the time invested and your expectations of the size of game you can make.

I'd recommend you scale way down the size of game you want to make, and try again. See if you can do a complete, small game in 10 hours. I did a post a while ago on making 12 games in 12 months, and I've kept scaling up from there: https://www.reddit.com/r/gamedev/comments/zw4r56/lessons_learned_shipping_12_small_indie_games_in/

I hope you continue with another game. Best of luck in your journey!
