Smart Moves Alpha

Also, for level 24, a hint is that there is only one "dead end" where you cannot return from getting a chest. So as long as this is your last chest, you won't need the checkpoint for any other path. And there is a small glitch that can help or hurt you - if you open a chest before the spike animation finishes rotating, it will skip the animation for that action. So if you quickly can "move-move-open" a chest, the spikes will only change twice, going from safe > armed > up. This is not required for the level, but it can leave you stranded, so to avoid that just press the arrow keys a bit slower.

For anyone else stuck on Level 22, I don't want to spoil the puzzle for everyone, so I'll write the first half of the solution. Press these keys in order: Down x4, Up x2, Right, Up, Down, Up, Right, Up. This clears the first wave. Then press Up x5, Down x2, Up, Down, Up... Pay attention to how the enemies moved for those last few commands, and the rest of the level should come together.

Level 22 is REALLY unintuitive, and really the only "difficult" level. There's no checkpoints, so the level is designed for you to lure the enemies in, but nothing about the level tells you HOW to lure them. The chests seem important because they can be used to burn a turn, but in this case they are useless and should have been placed behind ALL the enemies, so the player doesn't think "I should go for them." Really, the level comes down to binary thinking and recognizing how enemies interact when they want to move to an occupied space, but nothing in the game has reinforced these techniques.

I'm still stuck on lvl 22. Can someone give me some help please?

You call this an alpha? It's already a pretty neat game!
