This is a good game. I completed it AND got all the bonus coins as well. A very Klanoa type game. The level themes are visually done well and have their own fun gimmicks. It is a tough game though and I have my gripes with it. Like the player gravity is pretty high while falling, the leaf springs are a bit off, sections where you go down are hard to see, the inability to throw while facing a wall and the knock back on some items. Getting the last coin in volcano was a lot of trial and error since you had to distance yourself correctly just to be able to put the key in the door after the actual challenge. I think that's a bit much. Also a pause menu or an indicator in level to display collected coins would be nice as well.
Overall though, it's a pretty good experience and one of the more complete ones I'd played this jam!
