Thank you so much for the kind words and the input. It really helps us out a lot.
After entries for this contest are unlocked we do plan on going in and adding item interactions since it's the first thing people try after seeing the interaction notice (whoops, our bad). We'll also be taking a look at what we can do about button configuration and possible controller support, but that one might be a little trickier. We'll try though.
Thanks much for the input, really. We're all glad that it was enjoyable.
