Thanks! That would save the player from one click, but I wonder how long I should wait after a level has been failed before I reset it, sometimes the player might want to look at it to fully understand why he/she failed it.
I think it could work better if you had one prominent button to move on to the next level / reload. I found I kept completing a level, then pressing r instead of e - maybe it could just be space to do either of those depending on the context? Great little game otherwise though :)
