See the full list of the features here.

Dashboard — almost all the projects settings is located in one window
Node-based Level Editor — there is very flexible level editor. You can make many level fields in one level, change layouts right while it is playing by hiding and showing hidden slots, make tutorials with characters and hints. It is not just level design — it is visual level programming.
Three main match-three mechanics — it has three main match-three core mechanics. You can design your levels for swapping match-three, match-chain (when players need to draw chains of chip) or even match-click (when players click on a chip and it crashes with all the same chips that is placed near). There is no any restrictions — you may use different mechanics right in one level.
Bombs — currently there is three basic bomb-chips. A bomb that destroys near chips, one that destroys line of chips, and one that destroys all the chips with the same color. And all of them is customizable.
Bomb Mixes — the bomb can be mixed together to get more essential result. The mix pair and their effect are customizable using the main Dashboard.
Chip Generators — there is a few options how to generate chips in the slot. You can use default chip generator, that will generate only regular colored chips. Or if you need more complex logic of chip generating, you can use extended one. The extended chip generator allows to set a whole list of chips, setup them and set their probability of generation. You also can create a Chip Charge, that will contain a list of certain chips, which will appear in turn, while it will not get empty.
Obstacles and Targets — the project contains layered blockers, blocker-kind chips, layered jelly, sprawling blockers, ingredients etc. The list of this features will be grow with the next updates. It is also important that blockers can pass chips through themselves or block them as obstacles — it is customizable.
Goals — there is four basic goal type and a lot of their variants. There will be more goals in the future.

Star goal — reach 1, 2 or 3 stars
Color collection goal — collect number of chips of specified color.
Combination goals — make number of matches
Collection goal — collect number of specific items (chips, blockers, targets, etc)

Complete Bonus — when all goals are reached and player has some unspent movements, the movements transforms into bonuses. The logic of this ending bonus is pluggable as all other feature. It means you can choose what kind of bonus will be used in the level, or not use them at all. You can customize them as other level features and create new variants.
Gravitation — it is a great example of level extensions. It is a kind of plugin for the level editor, that allows to change chips falling direction for each of the slots. In the future updates we will have more extensions. Like Walls, which prevents movements between slots.
Chip Physics — one more kind of level customization is the chip physics. You can make one level where the chips will fall slowly, and another with fast chips. There is also two basic physics:

Straight — chip falls only down and can't to move right or left.
Realistic — in this case the chips will fall down or even flow down to right or left if it possible.

Integrations — the main Dashboard contains not only the gameplay editor, but there is a special Integrations editor, that allows easy to integrate all of supported plugins and pluggable features.
Localization — if you need localize your game for more then one language, it will not be a problem. There is special editor, that automatically scans whole the project and pick up all the localization entries which needs to be localized.
