About Heat incremental

From the creator of reactor idle, factory idle and city idle!

Your mission is simple: HEAT UP THE PLANET, Yes, really.

You’ll start with clean technologies like solar panels that barely produce any heat, but soon begin to research less clean methods to produce even more heat. Who knows—you might
actually succeed in overheating the planet.

Managing excessive heat, however, is not an easy task. Be prepared for challenges and, yes, explosions. MANY EXPLOSIONS. In your defense, explosions also help heat up the planet. Explosions cause financial losses and can bankrupt you though...

This game introduces new features gradually. At first, you’ll see only the basics to help you get started, but as you progress, more advanced technologies and mechanics will
unlock. It is a long journey with plenty to explore.

Disclaimer: This game is HARD.
It is also a form of a puzzle game, requiring you to figure out efficient strategies to improve your setup and boost your income.
Keep in mind that perfection isn’t the goal—you’ll need to focus on specific areas and make trade-offs.

Are you ready for the challenge?

Game is unfinished and it has been 9 months since the last update, so has probably been abandoned like the devs previous games. A shame; as it is otherwise a decent, if fairly involved, incremental.

Gameplay seems OK, It's hard to estimate how good is because A) I love reactor incremental games and am likely to have to give a game more praise than due simply because of positive bias I have for the game type and B) I don't have much playtime at all due to the main reason I can't recommend the game. The problem with the game is that there is no way to change the UI size. The bigger your resolution, the smaller the UI seems. It's a pain reading anything on the menus as a result. You may be able to make it more readable by lowering your resolution, but the game has no display options, so you'd have to change the resolution of your monitor every time you play. As of right now, the (mostly dead) discussion forum contains one request to add a UI size option from a year ago with no reply. The general lack of activity in the discussions section leads me to believe I'm not missing much by not playing it, Given that the game still has no UI size option, I doubt the developer pays attention to the discussion section and will probably not be adding the option in the future. To be fair, it's a free game, so it's not like the dev is actually getting paid to work on the game, I just c…

Generally When i Make these types of Reviews I would go into great depth to talk about it but i just wanted to make this short as possible. If you want my Honest Truth on this game it's truly not perfect Although it is completely playable and it's free. (IMPORTANT NOTICE) There is NO DLC in this game. There is also NO HIDDEN DLC in this game. This game also has 0 Competition Features. The game is the game. I would recommend this game as a road trip game or a quick game to pass the time.. not something to invest into. -Complexocon Review- \Rating Score - Mediocre/

Heat incremental is a surprisingly clever idle strategy game because it gives me one of the strangest goals I have seen in this genre. Instead of trying to save the planet, I am actively trying to heat it up as much as possible while also keeping my entire operation from falling apart. I liked that absurd premise because it gives the usual factory and idle systems a much more playful identity. The main gameplay revolves around building technologies that generate heat and income, then constantly adjusting my setup to keep everything working efficiently. I start with cleaner methods that produce relatively little heat, but eventually unlock more extreme technologies. I enjoyed the process of gradually expanding my system because every improvement creates another problem that I have to solve. The heat management is what makes the game more interesting than a simple incremental experience. I cannot just keep adding production forever without consequences. Machines can become unstable, explosions can happen and financial losses can quickly put me in a difficult position. I liked that tradeoff because I am always balancing short term gains against the risk of ruining the setup I have w…

The Planet Coaster DLC catalogue closed in 2019, so there is no curve left to wait out. Our record shows the collection bundle costs far more than assembling the same packs one by one.
