I have walls to hit and lava and fireballs now. The player gets faster as time goes on but slows down if they hit something. If they go too slow, they are consumed by hot magma and in all likelyhood probably die!
I’m reasonably happy with the progress so far. It’s not much to look at but I’ve been tweaking values all over the place to get it to feel right. And that feels much more productive than worrying about whether my code is tidy enough or my graphics pretty enough, at this stage.
I’m going to put in proper win and lose logic, throw together a title and menu, and then it should be complete, gameplay-wise. Hopefully by the end of today I’ll have met my target of having a functioning game by the end of day 1.
