Nice idea, good level design, controls are mostly good but I could have done with an alternative jump button away from the left/right controls (my arm hurts now) and maybe it could be a little easier to grab walls?

Took me 5:43
I liked the progression, it seemed hard at the start, but by the end the start seemed like it had been easy!

Within 5 minutes the whole play was covered with blood. ) Good reception - gradually increase the difficulty.

04:33... man, my SMB skills are getting rusty.
I liked your theme interpetation a lot, and controls were super polished. Neat simplistic graphics too.

Nice game, the gameplay is very polished. I guess you are a SMB fan!

Such a clever interpretation of the theme. Very cool, fun, but I couldn't finish. My room ran red with the blood of hundreds of me. Very nice job. Would be nice if I could have gotten a little bigger window.

Very challenging! That last layout was pretty brutal. The controls felt pretty tight, but it would have been nice if you didn't have to hold towards a wall to continue sliding off it, I think that would have improved the wall jumping a bit. Great entry though, perfect for speedrunners :D

Love it. Funnily enough we created a game with very similar concept, it was nice to see some different design decisions. Had a lot of fun, also it is very fun watching someone else fail at this :)

I made a competition during my birthday party for your game completion. First place got 1:16. The speed of the game really helped it to work for a party competition. Everyone had a blast. Thanks :)

Great job! This was short, simple, and super fun. Exactly what an LD entry should be like :) Controls felt perfectly fine to me. My first try was 1:26!

Only thing missing really is a great soundtrack!

One note of caution, with LD you will run into players of really wide variation in terms of skill levels, so it can be worth it to spend a bit of time working on more accessible (e.g. dumbed-down) versions of your game, otherwise it's hard for these other players to rate your game. That said, it's difficult to do that for this game type in particular =( Maybe you could make an easy mode where you can get hit once without dying?

Regardless, =I= thought it was perfectly fine :)

I was pleasantly surprised by how smooth this felt and how the controls felt. I would offer one thing: reset all the elements in the room upon death. It's really hard to learn muscle memory if the elements are at different positions after succeeding with a hard jump. I think having the elements all reset themselves after a death would've made it a bit tighter

Great level design, even if it was hard as heck; the difficulty ramps up nicely!
It was sad that there was not a bit of music to push the tension higher, but overall this is a solid entry! Controls were tight and it was fun to play.
The blood particles were great, my wife couldn't stop laughing every time I repainted the room a little more.
Congrats!

19:33 lol

great game, very tight and uses the theme to add something new and useful to one of the most common genres

my suggestion would be to try some non-symmetrical designs... the obstacles don't have to be the same on both sides just because the player is going back and forth

Really nice :) Some thoughts:

Blood effect - in meat boy all of the level gets red pretty fast, but here, because the background got red, it was more precise, and added up for each transformation.

Number on the level - Might be a idea to add a number, about the current transformation.

Additive level design - I have tried to do something similar, but only between smaller levels and its hard, but it works well here, well done :)

highs core 1:22 with controller, on the other tries the last level took a lot longer, like 1 min + 4 on the last level.. :)

I gave up after 9 min of rage inducing deaths!
Really well made I have to say, but the wall jump was a bit hard, at least for me..
Overall great job! :)

Oh and this was how far I got! :P

But for some reason all the blod disapered when I resized the windows from fullscreen.

Great little game, really tight controls and cool level design.
If I had a complaint, I'll the say that you could add another key for jumping (space, z) because all in one hand ends up hurting a bit. Ah, and also a bit more screenshake and feedback when you die :D
Great entry!

Very nice game.. Although I didn't have the patience to finish it and ragequit after about 8 minutes ;)

Challenging game! I included it in my compilation video series of the Ludum Dare 37 games, if you’d like to take a look. :) https://youtu.be/7yEaPmt36yU
