This level was a joke compared to the previous level, difficulty wise. Though these games are not often balanced difficulty wise. The previous level took me over 4 hours I estimate, easily for the whole level. The final checkpoint took me over 3-4 hours alone.
This level took me 19 minutes to complete. I got to the boss checkpoint on my first life, as youll see the edit takes place near the end. The boss was a little tricky and took some attempts but the level was over very fast.
It will be interesting to see if the other levels are as hard or harder than level 3. There are 6 levels left so there is still plenty of room for more brutality.
My assessment of the brutal difficulty was based on the third level alone, but from the footage ive seen some of the upcoming levels look like they may be very tough as well. I wont know until I try them for myself though.
Its safe to say if you complete level 3 you should be well prepared for the upcoming levels.
