Defend the Dune is available on Google Play. It's free, it's single-player, and it gives you a desert full of things trying to get past the defenses you just spent your last coins building.
If you like having time to think about a purchase and then watching a wave put that decision under pressure, give this one a try. Towers, walls, and recruited fighters all draw on your resources. You'll need to decide where the next bit of protection belongs, then live with that choice while the enemies approach.
The native Android builds are the versions I prefer playing on my phone. I hope you'll try this one even if you've already played on the website. The browser version of Defend the Dune is still available if you'd like to see what it does before installing anything.
What to build with the next handful of coins
The question I want a defense game to keep asking is simple: what would help most right now? Another source of damage is tempting. So is reinforcing the part of the line that nearly collapsed in the last wave. A fighter can meet enemies on the ground, while a tower supports the fight with ranged attacks. You can't treat those purchases as interchangeable.
Arrow fire gives you a way to keep pressure on approaching enemies. Splash towers help against groups. Walls and recruited defenders give those attacks time to work. A line that looks impressive can still have a weakness, especially if most of your spending has gone into the same job.
For a first run, watch where enemies spend their time. If they're surviving a long stretch of incoming fire, more damage may be useful. If a section crumbles before your attacks can do much, look at what is holding the enemies there. That gives your next purchase a purpose you can test in the following wave.
It's worth following a wave all the way through before deciding what failed. The enemy that reaches the keep is the obvious problem, but the useful clue might have happened much earlier. Did the front line go down quickly? Did a cluster absorb too much attention? Were you saving for an upgrade while a cheaper reinforcement could have helped? Those are the decisions the game gives you room to revisit.
A campaign with somewhere to go
Defend the Dune has a 101-wave campaign and four difficulty settings. The campaign gives you a longer target to work toward as you learn the different enemies and improve your defenses. Changing the difficulty gives you another way to adjust the challenge while you're getting comfortable with the economy.
I'd start by learning what each purchase actually contributes. It is easy to judge a tower by how busy its attacks look. Watch what happens to the enemies it is hitting, and how that changes when it has support. A defense that survives comfortably is giving you information too: you may have room to spend elsewhere in the next wave.
At the end of the campaign is the Cosmic Leviathan. If you've encountered it in another Legitsauce game, you'll recognize the creature. Here it has a three-phase fight, with changes in form and tactics as the battle progresses. Reaching the finale means preparing for a defense that has to keep working through those changes.
I like a campaign having a specific destination. It gives the upgrades and repeated attempts a shared purpose. A difficult wave can be something to solve on the way to that final encounter, and a stronger run can show you how much further your current setup will carry you.
The upgrades you keep
Earned XP pays for permanent upgrades between runs. Reinforced Walls improves durability, Coin Reserves helps your opening budget, and other purchases strengthen your fighting options. That creates a second set of choices alongside the coins you spend during a battle.
If the opening feels too tight, look at the upgrades that help you establish a defense. If your line survives the early pressure but struggles later, consider what would help it hold up or deal damage. Picking an upgrade in response to an actual failure is a useful way to learn what the game is asking of you.
Those upgrades are part of the intended progression. Better decisions and a stronger keep both contribute to getting further. If a particular stretch starts to feel like a long wait for enough XP, tell me which wave and which upgrades you had. That is much more useful for tuning the game than a bare report that it gets hard.
Playing on Android
The battles use landscape orientation, giving the defense and its controls room across the screen. On a phone, I prefer opening the installed game directly and having that space dedicated to the battle. The web version remains handy for sharing a link, and it will stay available.
I won't promise the same performance on every Android device. If you notice stuttering as a wave fills up, or a control feels awkward to reach, include your phone model when you report it. Knowing whether the trouble starts with a busy battlefield or is present from the menu helps narrow down what needs attention.
The ad rule applies here too
The current Android release is ad-free. More broadly, as long as I own this company, there will be no video ads in our games. Ever. That includes rewarded videos for another attempt, extra currency, or an upgrade. Getting through a defense game should never depend on how many commercials you're willing to sit through.
If I add display advertising later, it has to stay non-intrusive and clear of the controls. A wave ending should leave you free to think about your next move. The same goes for losing: you should be able to work out what happened and decide whether to try again without an ad taking over the game.
Help me improve the next run
The most useful feedback has a little context. Tell me the wave, difficulty, and defense you were using. If a purchase felt pointless, tell me what you expected it to do. If an enemy was difficult to understand, a screenshot can help show what was happening around it. Please leave personal account details out of reports.
You can reach support through the Play listing. An honest store review is welcome too, with whatever score reflects your experience. I'd especially like to hear whether the game makes you want to change your plan and start another run after a loss.
