Nice concept! Having different actions in a cycle to use at specific times is unique. Collectables and breakable objects on the map made for some good variety. The Dragoons are cute!
In terms of feedback:
For the attack, I wasn't too sure what the hit box was, so it was hard to use on aerial enemies. It was also hard to use as I had to time the jump and then get the attack right beside the enemy.
For the "D" action, I figured it was dash, but if you don't click a directional button, it does nothing. So I was initially confused.
For the chain actions, it seems that the verical velocity doesn't ever get reset, so it just constantly stack jump height and speed whenever a cycle finishes. I ended up just spamming the spacebar until the character jumps up so high and was able to clear levels that way.
