Fun game! Short and sweet. Reminds me a bit of the game VVVVVV. Music is REALLY nice. Thanks for making the game :]
I used the Godot game engine to make this game. I've also used Unity and GameMaker in the past. So far, I've enjoyed Godot the most out of the engines I've tried, but it's very much a personal preference thing.
I spent a lot of time agonizing over which tools to use in the past, trying to choose the "best" one. But I think what matters most is just starting to make something.
My advice is to find a small existing game you can copy and possibly add some of your own ideas to (I made an Asteroids/Space Shooter clone for one of my first projects). It may be less exciting than making a whole unique game from scratch, but there are a lot more resources and tutorials available if you get stuck.
Game development isn't easy and it takes much longer than most people generally expect to do things that might seem simple from an outside perspective. But it can also be an incredibly rewarding experience. Good luck, you've got this!
