Only if people would give me good suggestions.

use unity it is free to use and easy to work with

Use Unity Or Unreal Engine 4 They Are Both Free But I Would Suggest Unity Because It Is Easier!!

GameMaker and Stencyl are some other lightweight options

I have a trash computer and I am using Unity, and currently trying Flax.

ok bye

unity easy lightweight and won’t take long to learn c# is also much easier

I recommend Godot. Over unity, Both easy to learn but Godot has a much cleaner interface and straight forward workflow. Not to mention its a truly free Game Engine. i.e No royalty payments after reaching a set profit threshold
