I'm a big fan of Construct 3. I like how intuitive it is, how quickly you can make progress and try out simple and not so simple ideas. I even like it's limitations.
I like spinning up new projects frequently, quickly trying out new ideas. If something sticks, it will probably end up here.
My first public game prototype was called Gravity Unlocked, I've made it for a game jam. It was a great experience since I've finally made something I wasn't completely embarrassed to upload publicly.
At the moment I'm working on a new game prototype temporarily called Level Editor Mayhem, which is a 2D couch multiplayer platformer game mostly inspired by Ultimate Chicken Horse and Super Crate Box. This time I'm also writing a devlog so anyone can track the development progress and possibly give me feedback on the direction.
