Much more an activity than a game
I love idle games and play them all the time. What makes an interesting idle game is player decisions: typically there are multiple things you want but you have limited resources. Often you have to make strategic decisions to get those resources. This game has none of that in the core gameplay loop. In a plane, your only decision is “Do I reset now or wait for the multiplier to get bigger first?” Then there’s 4 planes. Then you can reset all of that to get a resource that you can then convert into another resource (without choice) where you can “buy a bunch of upgrades and provide minor boosts”. So after several hours of the main activity, you can get boosts to increase the speed of the main activity. This game seems to be for people that like watching the numbers go up alongside pretty colors. If you are looking for the strategic decision making found in all good idle games, be warned that it’s not in the core gameplay loop, and you’ll have to do a lot of repetitive resets to unlock anything resembling that.
