I did it! :D It took me around 10 attempts, but I finally did it. It was crucial to save a lot of time by being very efficient in the first easier half part of the game, so you have some safety bag in the later part. :)
I enjoyed the game in its current state, and it can be even better with a polished controls. Maybe a shift for a “careful step” would be nice, where you can move with 25% speed, but never trigger a bad cell. This feature is needed to align yourself properly for a jump without stepping into a pit just because you pressed a movement key for 1/60 seconds more than you should. :D
