This was a lot of fun! The timers are extremely tight, but there were enough spikes that they weren't too difficult. I wish there was a bit more of a tutorial, though---I was stuck on level 2 for a while before realizing that the spikes heal you, and I only figured it out by accident, which isn't a very satisfying way of discovering mechanics in my opinion. Overall, though, this is a great entry, and I enjoyed it a lot.
