I'm conflicted with some of the gamestyle. Wish there was some more idle features rather than just researching something offline. I haven't made it to tier 3 yet and have been playing for days and tons of upgrades. I do notice upgrades help but very slowly. Overall so far in the early game its fun and engaging enough. Easy to understand. Just slow moving with progression. Cost of upgrades get higher faster than you can progress for example. I'll keep playing and overall I enjoy it.

I LOVE THIS GAME! I mean it. The slow pace at the beginning might annoy a few people, but for me, it was a very nice dive into the mechanics of the game and learning what to prioritize and when to spend your gems. It drops off right at the perfect time when staring at it gets stale and becomes a more macro incremental game with the added benefit of keeping me from checking social media on my phone while I'm at work.

No forced ads. :) The start is a very slow burn but if you pick the right permanent upgrades to invest in, it speeds up pretty quick, and at lv 10 the turbo starts to spool and you really get that budget growing. Managers really start to pick up as it becomes easier to get gems after lv 10, and the manager bonuses can be very strong with a bit of luck in the draw. The developer responded quickly to my feedback, and seems to be working hard to make the game fun and frustration free.
