You have come up with a very interesting game concept. The implementation is good. Nice graphics and nice music, but a little harsh. It seems to me that it is inconvenient to run to the place every time after pressing the shift key. Overall, the game is awesome!

Played this with my kids; we all enjoyed the character sprite - particularly the smile face on there definitely making for a charming presentation.  The jump mechanic could be improved by maybe instead of having a linear velocity try a parabola over time; it'll make for much smoother motion.  The merging idea was neat; there were a couple places I thought a checkpoint would have been appreciated but - all and all - this is awesome work for such a short period of time!  Nice job!  :D

Nice game:

Pros:

The gameplay is fun and simple

Graphic are good.

The music was nice.

Cons:

There should be sound.

There should be a squash and stretch.

The later stages should be a bit easier.

A good idea for the merging. Controls could be improved, specially jumping in certain parts.

A very polished game, merging was well executed in my opinion, there is a variety of platforms to tackle and the game is very fast in terms of respawning and checkpoints, it works as you'd expect it and I appreciate that, a job well done!

Good idea, but controls should be more tight I think

the music loop is a bit too short and I think i've reach the high limit our something... can't put any blocks ;(

The concept is good but the process of spawning and switcher to another body can be a bit smoother.

it gave me some challenges I liked it !
