One more suggestion. Even when youre killing at your fastest. i.e. some x per hit monsters, they will still occasionally show that they dont have 0 health. This means that i cant intuitively see when im no longer killing that x per hit.
When I reload the game my attack speed says 1 until i invest in attack speed perks, im unsure if my guy is using 1 or the actual attack speed until this point.
most probably it's the 1 since when auto save kicks in it saves the last known attack speed and that attack speed is being used to calculate the offline progress... maybe your just ascended then closed the game before the auto saved kicked in? you can always see the last time saved at the bottom of the animation so I suggest you close the game a min after your last task just to be sure
Yeah the game UI was not designed for the small window that kongregate gives you. If you're struggling with it you can play it on my site http://dopeslinger.gti.nz/ with a lot more space.
The screen gets quite overwhelmed when your start selling a lot more drugs. The UI could be cleared up a bit. For example upgrades for drugs could be made into simple boxes inside the minimised bars.
