Congrats on shipping your first game! Seriously, that’s a big deal. Be proud of yourself, and don’t let the rough edges get you down.
Keep making games. The fastest way to improve is to just keep finishing stuff, over and over. Every project teaches you something, and the next one always comes out better.
Also, your art style is really nice. It makes your game stand out right away, which a lot of beginners don’t have yet.
And yeah, do game jams. They’re great for getting eyes on your work, and you’ll get way more feedback than you would otherwise.
Good luck, and keep at it 👍
