Stumpy Games' Spore is a... a... hmm. It's definitely not related to that other game called "Spore", but other that that it's a... Well, let's walk through this together. The game takes place upon a miraculous spore-world floating in a glorious cavern, which you must defend against the meteors that come crashing towards it. So it's a tower defense game, then. But you must do this by clicking on and shooting at the meteors, which clearly makes it a shooter game. But what's this? You have autoclicks, and the spore-world grows stronger as time goes on? So it must be a incremental game! Gah! Let's just say that Spore is a wild, unfettered, genre-blending arcade game, and leave it at that. Rapidly click on meteors to defend your fungal homeworld, and button mash on the glowing clouds to give yourself extra powerups. Keep the spore safe, and it will start to grow energy-shooting plants that will take some of the load off your fingers. It's a fast-paced, addictive, and very, very glowy game, and beyond the difficulty of pinning a genre onto it, it's quite an atmospheric experience.
Spore is designed to be played in short bursts; the "campaign" isn't very long, and each round of the game starts you from the first wave of meteors, without any defenses on your little world. But rather than put you at square one each time, the game treats its "achievements" system as a way of gaining power-ups. Prove your prowess at rapid clicking? Your clicks gain a wider area of effect! Keep your planet alive long enough that its defenses launch a lot of hits? Those defenses get stronger! Even when you don't survive every wave, this system still means you make progress and grow stronger with every attempt. It also contributes to the game's clicktoy-like nature, where you get incrementally stronger simply with time. It's a great incentive to keep trying, if you're not already motivated by the game's softly luminescent visuals and dreamy music. Unfortunately, the game's love of bloom and particle effects mean that it can slow down dramatically, even on lower quality settings. It's a bit of a shame that the frantic later waves can chug so bad in the framerate department, because the game is really at its strongest when it's most chaotic. Moving rapidly between destroying meteors and clicking power-ups out of clouds, making snap decisions on whether to destroy a rock yourself or letting your planet handle it... It reaches that kind of hectic Zen that all best arcade games achieve, especially once you unlock the truly arcade-style Endless mode. It may not have the smoothest sailing, but Spore is anything but moldy.
