Anyhow, I still couldn't visualise how to encircle effectively. Especially against a much more numerous enemies. The best tactics I've been employing so far is hit & run. Somehow, I clear floor 8 wave 6 boss with this pitiful stats.
Talking about stats, some stats make sense to me while others don't. Attack is simple enough. But health? Does that indicate your units max health? If convert's value is higher than health, will it be capped by health? Also how does heal differ from regen? How big is heal effect radius? Additionally, I couldn't really see heal & regen impact since individual units are so small. Adding individual health bars is probably not an option.
However, I do think a health visualise system could be created. What if the color of blob player controlling is gradient of health bar? Well, currently the player is red. But what if we allows each individual units to change its shade from red, to dark red, black the lower its health get?
Alternative color: make the player green at full health, then make units gradually change color from green to red the more damage they take.
This should help player see the effect of enemies damage, and heal & regen stats when they took effect.
