Hello! I am most glad that you enjoyed the game! Thank you for your feedback very much!!
I have noted the different points, and I most certainly agree with you on the 'small request', one thing that I haven't seen in most Changed fan-games, is the Post Transfur Gameplay, 'what actually happens once you are assimilated?', so a HARD YES on that one, I will be expanding the Post Transfur Gameplay, adding custom dialogs and probably custom events once you are transfurred and let the player decide when to go back to menu and try again.
As to the other points, the reason running feels like... 'grandmother running'... is because there are no effects, I will be adding FOV effects and other tinyitsy details, and will try to upgrade the feeling and use of running.
I have removed the JUMPING, (at least internally, once I post an update with a download you won't see the Jump anymore). Jumping just changed the concept of the original game too much, and I really did not see it as something really important that should be there, so yeah, it was there initially because I forgot to remove it and was focused on fixing bugs.
I've received various feedback regarding difficulty, so I will be trying to adjust difficulty for the different dangers: White Knight, Ming Cat and Laser Room.
Once I get back, I will check my To-Do list and start working on all the million tasks that I have pending for the Office Area and the feedback that's been given!
