This game has some of the most devilish puzzles I've seen in quite some time-and it's in Twine! Twine puzzlers have been getting far better in recent years, and this author has already been one to push the envelope with last year's game Lux.
In this game, you play as an intrepid (but tiny) alien, who must fight against 3 opponents. I thought this would just sort of be a combat game, but very little of the game is actual combat. Almost all of the game is exploring and using inventory objects.
Most of the early puzzles can be solved by changing your color. This strategy is used in man interesting ways throughout the game (although it would have been cool to have a call-back to it at the very end!). Later on, you gather a good deal of inventory items, each of which can be used on any scenery object and on each other, for a quadratic set of possibilities similar to Robin Johnson's games.
This game isn't perfect. I thought the opening was really long and non-interactive, but then once I realized the true scope of the game it made sense. Conversation is just lawn-mowering, which can get tedious. Guessing the exactly correct combination can be hard at times.
But I think this will do very well overall.
