I had loads of fun participating and managed to get something through the gate, although it was missing a lot of the features I'd planned to have. There were 7 participants, and I guess 1 of us was our host, so how did the rest of you get on?

For some reason I thought I had till the 29th, but luckily I checked on Friday. Spent 2 late nights to hack the basics together and then uploaded on Sunday.

Stuff learned:

Lots about sprites. Coming from Flash this was the first time I actually used a sprite sheet. Now I just need to go back in and realign everything.
That kiwi.js and phaser were created by the same guy.
Prototyping is worth it. I made a simple prototype in Word, but it saved me having to constantly shift things.
Also, a design document. Planning well really saved me when I was running out of time to code.

Stuff I'd do better next time:

I'd try get a more polished game out. Even if I can't get more features done. The fact that stuff doesn't line up really hacks me off.

Listening to:

I felt very rushed at the end - in spite of me thinking along the same lines that I would have more time over summer, sports day, speech contest and training new ALTs all conspired against me. That said, I'm super pleased with what I got out in the end.

Stuff Learned:

How Game Maker works! It was a whole bunch of fun and a very fun program to play around in

The importance of planning the flow of your code blocks - the simple coding I was doing in-block was ok, but planning as to where you should put a block of code with regards to when its object would be triggered/etc was an experience

Better Next Time:

Create more from scratch! I wanted to do my own audio and stuff, but just did not have the time
