Thank you! Not finding the critter, sadly, sounds like a bug - there's only so much time for testing in a jam. If I may ask, what is your native language? I am not an English speaker myself and apparently many people have trouble with my word games ;) which is understandable if a lot of non-natives meet in the middle.
Great suggestions. I will put them on the list for a possible full release. And I love that you like the key controls - as a beginner programmer, such details are a lot of trouble for me, and it's so great to hear they pay off!
