Thanks Dubhan!
The sitting on the first screen I thought I had covered: after a number of seconds (I think 30), a message suggesting to go into the hole pops up (it actually says whole, which I found out after release and was too lazy to fix). But it might take to long to pop up. I had this same comment from 2 other people, so obviously an issue to fix/adjust.
Same with the slow powerup, multiple people say that doesn't work well. That was my gameplay element for the jam's theme, but it looks like it didn't work so well. I'll keep that in mind for a future version.
Glad you enjoyed the game, and thanks for the detailed feedback!
