Thank you for the feedback, it truly is a gateway to improving the game!
So, what I am getting mostly here is that the Office area's difficulty balance is somewhat wrong, and needs to be balanced: big Dark Latex Puddles that are hard to go around, Dark Latex Monsters getting you too easily because they leave too little space, Bathroom monsters getting out too quick... I will get my hands working on the balance then, because it is not too much work because it is only modifying some variables that determine the difficulty.
As soon as I consider the Office Area stable and ready for release, I will continue to work towards the Dragon King Boss! (though, is it not a Dragon Queen? It seemed to me that it was a female on the original game...).
And yes, from all the modelling, the code, the balancing, etc., etc. that I've done until now, I might want to optimize, to upgrade, the game to have better 3D models, sounds, design, etc. when I reach the development of the Dragon Boss.
I am most glad you are enjoying the experience thus far, this project is very hard to develop!
