Answer 1

Interesting concept, but it's a bit too tedious for my taste; maybe it would help if it was shorter?  Towards the end I still hadn't gotten hit and it was getting pretty stressful! :)

Answer 2

I think so, too.  I wanted a lengthier level but it was artificially long; I think shorter falls + more smoothly flowing areas might work better.  I may revisit this.

Answer 3

Nice concept, but repetitive, perhaps having rooms with a combination of enemies would help mix it up.

Answer 4

I think I should forgo the room idea entirely, it's perhaps interesting traversing the rooms the first couple of times but really uninteresting thereafter.
