@gaspar: Seriously, read comments you retard. Stamina restores naturally (1 in 5 minutes for tier 1 critters). The energy drinks give you an edge over others by supporting the game.
@xanaset: Check if your critter has food. And tier 1 critters(the starters) gain 1 stamina every 5 minutes.
@member55: Yes you do, you just don't see it if you click before "FIGHT" has disappeared.
@Lancerwolf: The auctions are delayed sometimes. Just wait 5 minutes and refresh the page.
@Snailracer: When you learn more, it will involve strategy more and more. Learn about appendages.
If the developers rapidly expand the game (even if it would mean hiring extra developers) and get it a better dedicated server, this could be quite profitable.
Easy wins (Spoiler): Start out with a normal block, sticky block and poison block stacked up, fill the rest of that one stack with normal blocks. If you have the dmg boosting perk, use that and you're done, if not fill more stacks with sleeper/sticky blocks with 1 empty space in between each stack. this = win
Cruisers might be strong but they're slow and expensive too. In games like this people tend to spam in 1 lane(like the comments suggest), but after experimenting a bit I found out that multiple lanes work WAY better. For example: 1 ion frigate on every lane, and dividing scouts among these lanes will ensure a quick win without waiting until you can use cruisers.
Would've given it 5/5(I gave BTTD 1.5 5 stars), but the monster-flying-off-the-screen bug and the ghost bug are just too big to ignore, especially with the perfect win badge. So sadly, 3/5 for version 1.
Ideal set-up for both hard badges: Neraine, max agility, rest into power. Get beelzebub (only azure stones). Use deep blue(obtain as gift). Get grimreaper(skulls from cancer). Use the sword-attack. I beat zodiac master without using good items(2 of the beginner health vials only) and creator without using any items this way.
