Here's another GIF showing the new abilities that I put in this evening! None of which were the things that I intended to work on this evening, but still... (You might want to give it a minute, as it's 8MB - the image above is just a preview.)
I'm already beginning to see this as "Crystal Towers 2 done right" - I'm still proud of that game (after all, this one is directly based on it), but it had a lot of awkwardness in the system which came from not having any experience writing a game of that size. This time, I'm getting the opportunity to correct a lot of the mistakes - for example, the "boost"-style ability is now activated with a quick double-tap while in the air, rather than having to be selected and assigned to a spell key, and the general platforming experience is a lot more fluid as a result.
