Tafelmonsters! is an app for iOS I created for Malmberg when working for IJsfontein Interactive. The objective was to create an app that would facilitate memorising multiplication tables. The game was created in a month by myself together with Tim Groeneboom (programmer).

In Tafelmonsters! Players have to feed a candy to an approaching monster. The monster is hungry for a candy that has the solution to the multiplication sum that he is calling for. Players can drag or swipe to throw the candy with the solution after they selected the solution from the number bar above the candy. For this App, I came up with the concept, UI and game-design. I also monitored a play-test which helped us to create the user-interface inserting the right answers on the candy.

During the play-test, I found out kids don’t have any knowledge of a conventional input interface like a calculator. Therefore, some kids insert 7 and then 1 when they want to enter 17 since the dutch pronunciation is ‘seven-teen’.  To allow kids to handle the input that way, we enabled them to insert singles first and decimals later OR vice versa.

The app was released in 2012, although it is still prominently used to this date. It also was also selected ‘Best Educational App’ by Volkskrant (Dutch newspaper) and eduapp.nl.

You can download it from the iOS App Store.

 

Back in 2011, a small indie game emerged called Mr. Kubus. Together with Christiaan Bergen (Programming) I created a small puzzle colourful platform for iOS. It was my first game for touch. Mr. Kubus was downloaded over 10.000 times. It was even the most-downloaded free title during a special promotion!

 

The goal of the game is to reach the finish in time while collecting as many hearts as possible.The challenge is to move and avoid Mr. Kubus. Players control the protagonist: Mr. Kubus by rotating him to one of his coloured sides. Depending on the side he’s currently on, Mr. Kubus will jump a certain distance and height when the corresponding button on the left side of the screen is pressed!

I came up with the concept did the art and game-design of Mr. Kubus. It’s amazing to see Mr. Kubus is still downloaded today, although it hasn’t been updated to Retina graphics.
