Played these, and I like how you incorporated pretty precise jumps and timing, very well done. Complaint would be the "path" isn't very clear and the levels aren't easy so it leaves little room for exploration...especially on Precarious. And the use of ramps and slanted tiles really doesn't mess well w/ the difficulty, and it makes them more of a hassle than need be.
But anyway, great stuff and hope to see more from you.
Thanks! I will probably be keeping slanted tiles to a minimum in the future since I totally agree with what you said and mainly used them because they looked nicer.
