As a typing challenge, it was quite well made! I liked the gimmick of having a little guy run across your screen instead of the more 'professional' methods that a typical typing challenge uses.
I did run into a bug: On hardcore mode, on the final stage, even though I typed all the keys the little guy still died.
Also, this isn't fully 1-Bit. The stars in the BG aren't B&W.
Thanks for creating!
