Did you build this in HaxeFlixel? This is the first time I've run into a game on itch built in it, how was the process?
Yep, the game was written in Haxe programming language using HaxeFlixel engine. This engine does not have a graphical editor (only a fairly convenient debug menu in the game), the whole game is written in text editor (Haxe is better with VS code, for which there is an official extension), no dragging sprites or others (during development I almost did not touch the mouse). This may seem like something complicated and strange, but it's actually more convenient and faster than developing games in godot or unity, for example. But it is very inconvenient to "draw" tilemaps in the code, so you have to use third-party programs (I used tilemap editor LDtk)
HaxeFlixel is a relatively minimalistic engine, which gives a lot of possibilities in customizing the style of writing code, which I really, really love
HaxeFlixel has open source code, so you can see what this or that function does without leaving VS code. There is also documentation in the code itself, which is displayed in VS code when the cursor hovers over a function or parameter
I recommend trying to learn Haxe and write games on it, I think you won't regret it. This language is very undervalued. The syntax is similar to TypeScript mixed with C#, but Haxe was heavily inspired by ActionScript
I didn't specifically remove the splash screen (HaxeFlixel logo), because I want as many people as possible to learn about this fabulous language
