any chance of allowing us to export saves? i clear cookies after each session so i won't be able to continue for too much longer. other than that it's pretty fun!
Hey thanks for playing!
It's on the plans, but we'rte focusing on balancing now, so it might take a while
It does'nt save, every time the site reloads i have to start from the begining
Sorry about that! We just fixed this issue and we'll upload a new version soon
triangles really fuck up the targeting man
You mean they get picked first all the time? You can change the target from Closest to Strongest or Random, and by switching targets the turret should fetch a new target instantly.
The idea of having them there is really to mess up a little :P
No, the tirangles never get picked until they're destroying my base resulting in it being impossible to heal
Oh, weird, we'll investigate that. Thanks for reporting
They don't switch targets once they've started attacking something which leads to the knockback upgrade not being that useful since they just let triangles go through and then that's it
Target priorities definitely don't work correctly. I have one gun on strongest and the other on closest and they shoot the same target almost 100% of the time.
Thanks for reporting, we'll double check that logic :D
♥️ thansk a lot
Hi, you have a nice base here, simple and to the point. Here my feedbacks:
Couple UI fix IMO:
About Gameplay:
Gameplay additions:
is by letting the player upgrade the enemies. Like making them harder to kill but giving out more money. (they should be able to cancel them to not softlock themselves)
I believe you have a difficult framework to work with here: Player agency is mostly comprised of upgrading firepower. And your leverage of balancing the game is enemies stats and costs. Meaning the balance is pure maths. Which won't really be fun for you nor for your players.
Of course maths are important in idle games, big numbers go big, one number goes many numbers. That's the juice.
Yes, you could start by making enemies a lot harder to kill or output enemies faster, since you don't really lose anything by dying except time. Unless you want a good player to "win" from a fresh save without reset.
But I think you should also find a couple other avenues for player agenda. You could have double edged upgrades for enemies. You could dig deeper into the idea of idle runs for money gathering and active runs to reach higher waves. You could add walls or zones at different level of the screen with other effects and cooldowns.
Good luck and congratulation.
Wow! Such an amazing feedback!! Thanks a lot :O
We're currently working on system to allow players switching the turrets, to make unlocking turrets and slots two separate things. We hope that this will give players a bit more chance to customize the game to their style :D
I'll add your feedback to our pipeline, thanks again!
Nice game, loved the graphics, enemies too slow on lvl 50, maybe increase more their life? congrats
Thanks a lot :D
We're working on balancing, and hope to make an update soon!
got past lvl 100 and then it got boring and tiresome. Enemies are too slow then, there was no challenge anymore. There is also too little variation in the enemy types
Thanks! WE're working on adding more content and variety :D
What is this strange tongue appearing on screen?

The language of bugs! 🤣
That wasn't supposed to appear like that, it seems there was a problem with the tutorial
Speed boost gets locked when making a purchase
Thanks for the feedback!
I got to Wave 47, then the game simply stopped spawning enemies. The balancing up to that point was way way too lax as well. The rate at which you gain more income outpaces the scaling of enemies by a lot. Especially the crit damage% scaling on the base tower makes bosses completely trivial, since that stat is incredibly cheap for being a multiplicative modifier.
Thanks a lot for the feedback!
We're working a lot on the balance, as we know it's quite broken now :P
There's a longer feedback form in the game, we'd really appreciate if you could take the time to check that :D
Cheers,
