Simple puzzle game, neat idea of balancing health and movement.  Well done! :D

Cute little puzzle game! I liked the concept of trying to find the optimal path to get the other end, would have liked to see more difficult levels or maybe other mechanics to go with it, otherwise great job!

I'd work a little more on the level designs, and adding more variety like different kind of blocks, but it is a nice game, good job!

The concept is simple but some levels make you think before bashing. You can probably introduce more interactive elements later so you can make harder puzzles.

I love the concept and wish I could've played more! I agree with the others below, some of it definitely could've been more difficult or engaging, but it was actually pretty relaxing. The music and sound effects were great too!

I actually quite like the concept and the clean execution, but I feel like the game doesn't explore it a lot? The levels are way too easy at the moment.

There're also a couple bugs that I noticed with the games: 

Music does not reset for restart, my god it gets loud after about 10 restarts.

The health bar is made from a long health bar and trimming it according to player's health, I notice this because there was a tiny bit that was poking out from the 6/7th health.

The first level has a bug where resetting does not reset the whole level, so you can break a wall, reset to checkpoint and walk pass the gap. I think this might be caused by the checkpoint because the rest of the levels works fine. Speaking of which, I don't think a game of this length needs a checkpoint system at all.

I like the core concept, but I think introducing one or two more mechanics could have added more depth - right now it was mostly just seeking out hearts without much thought. However, the game works very well as is, and it felt pretty fun to play :)

Short little game with good approach. You could make the character moving faster when the buttons a hold down so the player is not forced to pushing the movement buttons all the time to move fast. Overall a good game. Had fun. Well done! :)

Hi, great little puzzle game! It was relaxing and I think I'd play more with a bit more content. The premise is good, I like the nature of the puzzle elements and it did make me think a bit.

A couple of small things: One of the levels felt a bit long, I think it was level 3, where there is a lot of walking to gather hearts. I feel like it would have suited the second level better with slightly shorter run distances.

I also noticed a bug in the tiling of the health gauge:

Great job!
