I started again and got to lvl 10 with 29 deaths. All 29 deaths on lvl 8 :|. LVL 9 was real easy
edit: wow i just died 30 times to lvl 10. now its getting hard
13/14/15/16 were super easy. 12 was terrible

. oh my god, so is 17 ugh. 17 made me give up, ill try again later, see if I can reach it with under 30 deaths, having done the first 10 levels twice already it should be doable
