Mottzy's first ever game jam! This jam is focused on fun and is  a beginner friendly challenge to makers to make a block-friendly game.  All are welcome to go at it alone,  pair up, or create a team. This Jam is the lead up to Mottzy's birthday, and playing your games on stream will be a lovely gift to open. 

Find out more about the jam by joining the Makerville Discord,  stopping by the Mottzy Makes stream,  or checking out Mottzy Makes on Twitter!

To make the jam fun and focused, below are the limitations to encourage makers to challenge themselves. This jam is not judged, but will be more fun for everyone if we follow the required limitations


While there won't be "disqualifications" please follow this requirement to ensure we meet the game jam goals!

-- Make It Blocky! --

2d or 3d, think in blocks (because Mottzy is a real square y'know?)

There is only one challenge:

Game jams are a great way to learn and grow. To support those putting the effort in the game, general feedback should be given in a constructive manner to support the developer(s). When providing feedback consider the following:

  1. Identify elements of the game that worked well for the player
  2. Provide supportive language on theme and restriction elements
  3. Remark on the overall concept
  4. Provide thoughts on the interest of the game and how it worked for the player

Everyone takes feedback in different ways, if you prefer to hear feedback differently please make note of what you'd like to hear. Consider provide notes on the game, or directly to Mottzy for when he plays, on the following:

  1. Whether you prefer mostly positive constructive feedback, or would like some level of constructive / critical feedback
  2. Specific areas of the game you want focused feedback on 
    1. This can be helpful if there are unfinished portions of the game where feedback would be less helpful
  3. Scope of feedback - such as "general" or "in-depth"
  4. Any other guidance to help proved you the most helpful information for your game
