Ha-ha, I’ve only managed to reach level 9, given that I’ve obviously practiced a lot :) The game is meant to be somewhat challenging, and controls are part of that.
Yep, the terrain is basically a variation of marching squares. There is indication of certain events - usually just with a little explosion ball, - but you are right that it isn’t enough. I am currently working on sound & other effects, as well as improving the rewind mechanic.
Thank you a lot for your feedback!
