This was a really neat puzzle game! There is a lot of neat details in the game that just make it feel polished! I really like the heart rating system that shows whether you did the solution perfectly or if players can finish it with even less deaths (it encouraged me to go back and play the level again one time)! Also the sound effects are just really fun and playful (really nice touch)! The music found was also really nice to hear! The art style is really just pleasant to look at! It has this minimalist vibe that is really suitable for puzzle games in order to avoid visual overload! For the gameplay, the levels have a nice sense of flow to them! The tutorial level excellently teaches players the core mechanic of the game within seconds of playing, instantly showing them what they are going to get themselves into. Then, the following levels just slowly expand off of the mechanic and introduces new game elements at a nice pace, not to overwhelm players! The difficulty curve is really nice for this type of game, so good job! The movement is nice, but I feel like the margin for error for some of the platforming segments is too little in my opinion. This wouldn't be a problem for most platforming games, but this is more of a puzzle game where players shouldn't have to worry about losing a life and more worried about solving the solution (I had multiple instances where I would miss/barely make over gaps and spikes because I hit my head on the wall, making the jumps pretty difficult). The generosity for life giving makes up for that, so I think its more of a personal nitpick than an actual major problem.
Overall, this was a really fun puzzle game! There were a lot of fun levels to go through and I had a lot of fun with this! Hope you had fun with the jam too! Great job!
