The limit of units is 10, and it cannot be increased, it’s just something that wasn’t added because of lack of time. This and other stuff could be added with some sort of Research (from some Laboratory or from Nexus) – that was idea and never get in. The game nature is kind of “a lot of stuff is automated” so yes, you cannot pause Plant and you need to plan when to build it. It is probably better to have when you have at least steady 1,000 gold in the bank, so you almost will not notice it.
I get to about 14 wave and the tactic was – build turrets only (keep an eye on from which side enemies go and how many of them, so you don’t make turret at wrong side and has no money for correct side). I build plant after maybe 7-8 wave, second plant probably after 11-12. The idea is that units costs less than turret, but they rebuild automatically and they are mobile, so with larger base they will just move where enemy is. In terms of whose units is stronger – players or enemies? – answer is: they are identical :) Again, some more units should be added (when playing it is obvious idea) but as we have only 7 days, i spent time in other areas. That is why no enemy variations, not many different buildings no researches (unit capacity, faster roads, better turrets etc).
Maybe that crazy, but actually building progress (like time to build) was added in the last day, maybe 8 hours before jam end. Before that building was instant :) and let me tell you, there are strategies/cheating like when you just insta-rebuild same mine so enemies are staying in place :D – that was not looking good. I had two ideas: block building ability while enemies around OR to add building time so it’s not possible to just rebuild 10 times in 10 seconds same node… the building time is more natural i guess, so here it is :)
Thank you for the feedback! <3
