Maybe a road type (end game) which costs blocks, copper bars, glass, and plastic (like 50 of each or more?) and can transport all, like with modern roads (pipes and cables underneath).
I'm only in the first world, putting a few points into the third tree.
I like the game so far, and haven't come across memory issues yet. The starting damage/HP seem useless now. Could the level up attack/HP be % based instead? The starting stuff would be useful then. Also the combo trees (1st) usefulness is very quickly gone with the final upgrade on that tree.
I don't often give feedback but here goes (I'm on map 12 for reference);
- Blocking was useful for a few maps but is now useless. (Too low to make any difference)
- I'm one-hit-killing pretty much everything and should not be.
- I personally add nothing to production now.
- My Trimps will soon (if not already) give no real gains for production.
- I have a few upgrades of coordination but not nearly enough Trimps despite buying housing at every opportunity.
- Wood is very scarce compared to upgrade costs, and being able to get it from the main maps means I cannot grind some extra maps for wood. A solution here might be to have extra maps with only wood and gems as rewards, because metal seems to do okay (misbalanced still, but not nearly as much as wood).
As a suggestion, would it be possible to have alternate event times for those who cannot play at those times.
Many events happen at 2-4am which is not a time I can play.
