Wanted to play more from the dev of Kamiko so I played Fairune 1 through this collection. It's a very simple RPG with no combat until the final boss fight. You gain experience by fighting either the enemy the game tells you or the one that will come next. Fighting anything weaker will result in no XP gained and fighting anything stronger will result in you just bouncing around taking damage. There were a couple times I got lost, but that's mostly cause I'm a moron. The game's pretty linear with pretty simplistic puzzles. Going from Kamiko which had simplistic combat to this which has basically none was weird though.

Fairune
Completed twice, with 100% of achievements unlocked - includes 100% completion, 1-hour speedrun and zero deaths. Fairune is a somewhat simplistic 2D adventure game, playing out from an overhead perspective, with pixelart graphics. Combat in the game is handled through a 'bump' system, with enemies defeated simply by walking into them, at the cost of an amount of cost determined by the monster's level - and with monsters off too high a level instead killing the player outright. With this simplified approach, combat clearly isn't the core focus of Fairune, with exploration and puzzle-solving instead brought to the fore, to good effect. This creates a generally very relaxing experience, with exploration bringing a nice sense of satisfaction - perfect for its short length.

Fairune 2
Completed twice, with 100% of achievements unlocked - includes 100% completion and 3-hour speedrun. Very similar to the preceding game, this sequel is largely similar, but provides an expanded experience - gameplay is much the same, with the 'bump' combat of the first game retained, but the game is 2-3 times its length, with a greater number of different, themed worlds to explore, each individually larger, and a wider selection of equipment to collect and puzzles to solve. There's a little more plot here, though it's still very light, but overall, the expanded scope and variety of scenarios (in all key ways - location, equipment, puzzle types, etc.) means that the game justifies its longer play time, while retaining the relaxing and satisfying feel from the first Fairune.

Fairune Origin
100% of achievements unlocked; zero-damage, sub-6 minute speedrun. The first of two 'bonus' games that round out the Fairune Collection, Fairune Origin is a very short-form take on the series' approach, retaining the 'bump' combat but now making its outcome based on the direction of attacks, and taking place in a much smaller area. With 100% completion attainable in minutes this is very much not build as a lasting experience (though there's certainly competitive speedrunning potential), but it's an enjoyable if very simplistic 'palette-cleanser' after the lengthier experiences of the two main instalments.

Fairune Blast!
100% of achievements unlocked; cleared with all three characters. Fairune Blast! is the second 'bonus' game in Fairune Collection, only unlocked after beating the three other games. Very different from the main gameplay of the series, Blast! expands on the format of the final boss battles of the two main games, being a vertically-scrolling shooter. The three different playable characters, each with different weaponry that powers up as you play, bring an impressive amount of variety for a bonus game, but with only a single stage, limited by a timer (each run ends at two minutes) rather than progress through battles, this is never going to last all that long. That said, with well-implemented leaderboards, the game does about as much as could be expected of it, and serves as a nice way to round out the Collection.
