Thanks for the feedback! I think maybe it's because it forces you to go horizontally before you have time to build up a vertical lead on the ink. I posted a version where the ink rises slower with an optional faster mode, so hopefully that lets people cross easier.
Thanks for the feeback! Yeah, I originally had it slower, but sped it up last minute cause I thought it would be too easy without enemies. I think 3 seconds was definitely too fast so I posted a version where it's back to the original slower time with a button for optional faster mode now.
