I badly need a WASD version, my arrow keys are a tad broken lol. Similar idea to our game, though, so there's a bonus point right there. I don't know if there was more to explore there, but I didn't really see how the size changing mechanic actually came into play. I guess you can go through some tight spaces when you're small, but that's about all I found. Would've liked to see some more reasons to change size! But you did it alone, so it's difficult to ask for such things, definitely not bad for a single person and 4 days!
