So, I've been bad. I went about 4 days without making any progress because I went way too ham the first few days and burnt myself out. Today I finally got myself to look at Construct again, and worked on some sprites. Lots of minor things, but I need to ease myself back in. The long break is making it clear that I don't think the game will be 'done' by Saturday, at least not how I want it to be done. Like, I haven't even figured out how to do dialogue, which is a thing the game will need.
And I'm pretty bummed. And disappointed in myself. I have a habit of doing this - diving headfirst into something and then very quickly fizzling. I wanted this to be the thing that helped me, ya know, stick to things, and I couldn't even stay focused for a week and a half. But I'm going to do my best. I still have a few days to get this thing a little more complete.
Also, I know people like pretty pictures, so here's proof I've made progress: I made Satan's idle animations, finally! Will need a little frame rate tweaking, but I'm pretty happy with it. He's very fab.
