I've just released my first game here called Dungeon Climber and have added it to the Summer Sale! This game is similar to Getting Over it, Jump King, etc, where the goal is to reach the top but it's very easy to fall all the way back down. If you're interested, please give it a try!
All of the assets used in this game I got from itch.io itself, so if you're interested with what can be done with this site if you put in the effort to do so, I think this is a perfect example.
