Good morning!

We are looking forward to your games! Remember that testing is highly vital to any game. If you are still developing new features try to stop for a moment! Just play the game as it is, write down bugs, write down hard edges, write down things that needs to get polished. Isn't the list long enough already? Couldn't you do some smart game design decisions to cut off non-implemented features and just use what is already there?

Remember, 18:00 CET is HARD DEADLINE for submitting your game. Reserve at least 1 hour to do it as it includes page setup, exporting your game, confirming it works, not mentioning fights with ;-)


Good morning!

We hope you had a decent sleep! For the brain to work faster and smarter, we advise a light breakfast, cup of green tea or coffee and some bits of physical exercise. Effect is guaranteed ;-)

Today, you should focus on creating your early prototype, remember, faster you have the core gameplay loop, faster you can get to polishing, which really matters! See the 4:44 talk by iconic jammer Rami Ismail!

Do not forget to post some screenshots around noon! It does not need to be from the game, screenshots from IDEs are fine as well!
