Downwell

Opposed to Careful Descent, you need to complete an entire area (3 levels) unscathed to get the trophy. Completing mid-levels do not work (i.e.: getting Area 1-2, 1-3 and 2-1 does not count). As each area gets progressively harder, it's strongly recommended you try it on Area 1 on Normal.

Time your jumps and do not rush. Forget combos, and go for a paced descent. Kill enemies one by one and do not go for multiple enemies together, as you can land on a wrong spot and will likely need to start over. The trophy will unlock at the upgrade selection screen of Area 1-3.
