Last week managed to get past the 3rd Boss
Died 2/3 rooms later
However, immediately upon my revival I noticed an interesting change in the mansion
All the levels became more complex in their design
The 1st floor for instance, had a very "samey" layout that didn't chnage much no matter how many times I repeated - open halls with few enemies, a couple of corridors each connecting to 2/3 rooms
Now the halls have more enemies (but more cover), the corridors are tigher, longer, a bit less linear and connect to more rooms which sometimes don't allow for clear shots against multiple opponents
Floors 2 and 3 have become even more of a nightmare - specially the garden floor which features windows
So the more the player progresses the harder the entire game gets
Neat
Though regarding the combo meter and scoring, imo the game could've done better
The combo meter for instance only cares for how many enemies you've killed in X amount of time
It doesn't take into account what weapon you used, your precision, your perks, if you got hurt, if you ducked enemy fire, if you kicked him or if you used bullet time
And it's not like the game doesn't track this
At the end of each run you're presented with performance statistics, so there's definitely a monitoring of your gameplay
Which means the developer choose to have a simple scoring mechanic, either as game design choice or because he didn't want to bother...
