This is only my 2nd chamber design. The first one was so bad I have now hidden it! I would love some feedback if you guys have a few spare minutes. Give me some pointers if possible.

I have a new chamber up as of today! It's a precision map that will test your resolve! Please give me feedback on your impressions in comments!

I designed a new timing map design to be fun. It's not difficult to solve, in spite of the title's implication. It's challenge is in accomplishing what you know you must do. Please rate and comment.
