Really cool! I had a lot fun going through the whole game.

I truly enjoyed the different mechanics, the level design and the three different characters swapping concept. The music and sound effects create a very enjoyable atmosphere.

Just a minor thing that I wanted to mention, it wasn’t very clear to me how the characters unlock each other to continue their path, maybe a small animation would help.

Well done!

Amazing work on the graphics, music and level design!

I encountered a few bugs, like the character getting stuck while I was dragging the blocks, but nothing game breaking 

That was a really big (and long, cause I died a lot) game. I'm surprised you managed to do all this in a month. I was honestly expecting something else. I don't know what, butcertainly not the megaman 2 blocks from hell again.
Graphics are mostly consistent. The artstyle's simple, but the lighting and effects make it shine. There are some issues with visibility and readability, though, but nothing serious. Though, I wasn't sure what floors killed you at first. I don't even know if they're electrified or just spikes or something else entirely.
Collisions are a bit wonky. A smaller hurtbox than the characters (separating collision box from hurt box) would punish the player a little less. The grappling hook click sometimes didn't register for me, but that may be me.
I really liked the music. The sound effects are weird.
Overall I liked it. It was harder than what I was expecting, but that's on me.

Really solid entry! It's really impressive how built out the environments were, especially since they're different for each of the three characters. It's cool that they all have their own tools and personalities, although it would have been nice to have more interesting interaction between them (other than just "I need X to progress").

Some of the hazards could use better telegraphing --- especially the lasers and the white platforms that change colors gradually. I liked a lot of the tight timing on the puzzles, but it would be nice to have extra visual indicators.

Great work for a jam!

Nice graphics, SFX and music, it goes well all together!

I loved the idea of having three differents character to play that help each others! Nice concept!

I just had troubles to make the difference between what I could jump on, what was just decor, and what could hurt me. Maybe you have to work on it to make it clearer for the player.
