And here goes a new update : Day 4 prototype.
I have read and considered your feedback, and (hopefully) answered it for the best.
The game is keeping some consistency and taking shape, I might be able to pull it off.
@UberLou: There is still the mousewheel up, but it requires less effort now, does it feel OK to you ?
I have tried to incorporate the "mouse up" movement, but in the end, it was more troubles than anything (or I did just not find the correct way to implement it according to the prototype).
Let me know your feeling on this current prototype.
Enjoy and don't hesitate to leave some feedback, I greatly appreciate it and thank you all again a lot for it !
