Great game, there are just enough different mechanics to make it interesting but not overwhelming! If you choose to develop this further (you should since it is a pretty solid game idea! :) you could probably get more juice and style out of visuals and sounds. You could also consider a mobile version, i believe it could work well on a phone... 

Well done!

This was a great puzzle game; I'm so glad I stumbled upon it!  I initially tried playing with the mouse, which was difficult but doable; but so much better on the keyboard.  The puzzle is really interesting here, and figuring out the right sequence to do the words in is really fun and addictive.  The addition of the bonus and crypto tiles is a nice little change of pace, too.  I don't have many notes here, since I loved just about everything about this.  My only quibbles are the lack of the sound on the title/menu, and the fact that the different music tracks, while all good, vary quite a bit in terms of style, which can be jarring when moving between levels.

All-in-all, though, this was a fantastic jam entry.  Lots of fun.  Kudos to everyone involved!

beat the game with a 9-4-2 on golds, silvers, and bronzes. super fun game and simple yet creative concept. i like how the locking mechanic forces you to think about which ring you move last, as well as how to line up certain rings ahead of time to count for multiple words. there's a lot of optimizations you can make to improve score, which i think is cool. aside from the mouse input suggestion others have offered, i think having a second or two to countdown and look at the level before the time starts would be a nice QoL change, just because how it is now kind of feels like you're being thrown into the level immediately and there's no room to quickly plan a strategy based on the words and the letters. just a nitpick though, fun game!
