This game was played in its entirety on a MacBook Air M1 8gb ram 7c gpu running MacOS Sonoma. There was one small bug, but no crashes throughout my time with the game. All achievements unlocked at their appropriate times. TLDR: A fantastic game that appeals to both tower defense and idle players. Its only minor negative is its short length, but otherwise the game was an excellent experience. I really enjoyed Castle Idler. It takes some risks and mostly pulls them off. It's a fantastic game that melds tower defense mechanics with a pseudo-idle background. The graphics are simple but effective. You can easily tell at a glance if an enemy is frozen, slowed, poisoned, burned, or hydrated. Each one matters, I swears! The sound effects are very basic and I found them inoffensive. A small nitpick is that the game is not really an idler, at least at the start. The game NEVER does anything offline. All progress must be made with the game running. This is a bit unusual for an idler, but it is such a short game that I don't think this is a bad thing. You do have to be active in the game at the start as nothing is automated.

Not so fun end game. Just number bumps but worst is the need for prestige to advance just one perk/upgrade.

castle idler is a incremental idle game where you gain killstreaks to progress to the next level. The gameplay loop is easy, get kills, upgrade and prestiege. There are also many ways to synergise your towers to get damage. It was rather fun at first but got a little tedious towards the end. Sometimes you have to get a certain strategy to progress. It was still quite fun.

Not a bad game. It's tower defense with Idle mixed. With prestige system you chose what upgrades you want base on your build.

Undertale's own listing calls it the RPG where you don't have to destroy anyone. Games like Undertale that keep that idea: permanent choices, fights you can talk past, worlds that notice.

Most games like Slay the Spire copy the cards and lose the map. These keep the risky-or-safe choice, from a three-floor train to a deck made of poker hands.

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.
