I have been making good progress so for working on my 2d platformer engine.
However, as I add ennemies and traps, I realized that it is not enough to make a good game. I have studied some similar games like the first Castlevania on Gameboy, and I want to take some time to think the game. I will make slower progresses on implementing new things from now on. It is also a big project if I want to make a decent game, and I will focus on smaller and shorter projects.
