I really love the aesthetic of your games. Would you mind sharing what tools you use to create them? I've been interested in spending more time on game development as a hobby recently.
Mostly Unity3D. I've amassed a huge list of assets, shaders, plugins, vfx, and tools that have aided in my workflow. It's hard to think of all the tools I use within Unity at the top of my head. I might make a blog post one day about my workflow but for now this is a pretty good starter list to get you started:
By the way you may want to consider Godot as a starting engine. Not only because it's open source (so no shady business practices), but it also is focused on being specifically a game engine. Unity tries to be an everything engine and has lots of broken, bloated, and unfinished features. The simplicity of Godot adds a lot of much needed constraints to development. You're not constantly wrestling with the engine. I'm deep into Unity now but if I were to start all over I'd go with Godot.

and if you need free assets, I made a blog post about creative commons resources.
