Adventure Game Studio

Games like Monkey Island and Maniac Mansion ended up defining gaming for an entire generation of players. Adventure Game Studio is an application for creating your own 2D adventure games, otherwise known as point-and-click adventures, with the same look and gameplay used during the 80s and 90s. AGS has a pretty visual interface as well as its own scripting language, so you can design your game down to the very last detail, including all the rooms, characters, and objects you interact with as you play. Likewise, you can use any image-editing tool to create sprites and backgrounds for the game. Although it may feel a little overwhelming at first, there's a huge community of users to answer questions and give advice, as well as a few tutorials, both official and otherwise. When you start a project, you can select the controls you want: the SCUMM verb system used in Lucasarts games, or something more like AGS or AGI, which was used by Sierra. You can also use nothing more than the primary and secondary mouse buttons, like in Westwood games. The possibilities are endless. That said, you can always modify your game until it's exactly right. Adventure Game Studio is a fantastic application for creating your own video games. Although it's not as intuitive as other applications with drag-and-drop capabilities, it's still easy enough to understand.

Spooky Hat Shop

22 Studio

Spooky Hat Shop is a casual game in which you oversee a hat shop, where the owner is Death, and you are its fellow servant. The main obstacle will be the storage room, which is full of challenges and chaos that will hamper your main goal— to create cute hats and sell them to spooky spirits. It is a game that mixes store management with the casual and dungeon crawl genres in order to create a fun pick-up-and-play experience where you can dive in for 10 minutes as well as 2 hours— all while enjoying an aesthetically pleasing spooky cute art style. In the bridge between the living and the dead, Death decided to make a hat shop for the misguided souls so they could enter the next world with class. As time passed, Death felt the number of working hours in her body, so she hired an intern to do her job while she could go on vacation. The store turns out to be very cozy, bright, and spacious, although somewhat cluttered due to the protagonist's personality. In this area, you will find customers milling around while waiting for you to make the hat they so desperately need. In addition, you will find the portrait of Lady Death, with whom you can talk at all times, and to which the protagonist has built a kind of altar to worship her. Finally, behind the counter, you find the back room or work area, where you will have to create the hats using the requested ingredients and the different crafting tables.
