I made a short lil level just now. Six rooms in total, was fun to make!
The screen transition effect is nice, but it can be pretty obtrusive to gameplay, especially when you're going from one screen to the next fairly quickly. I'd recommend either shortening the length of the effect or making it delay and save previous inputs La-Mulana style.
this is beautiful. i love the vertical brick checkerboard.
i agree with you about the transition effect. i think perhaps it could be improved by either pausing slightly at the beginning of the transition, or having a region around the player which is forced to be clear.
on down the road i'm planning to have a set of different transitions to pick from (and the sprites used by the transition will also be customizable).
