Nice game with simple and effective graphics, good job, definitely has a lot of potential to be continued! A special shoutout to the ability to control music and sound playback volume, a very nice QoL touch for a jam entry. Very good entry!
I concur with the previous speakers that the movement is a tad too fast, especially when constantly having to switch to the much slower paced "place the platform" mechanics. The levels could also have been a bit shorter at the beginning, it's hard to do a series of tricky jumps and then fail on a later ones, it's just not much fun to repeat stuff when you've already "solved" the puzzle aspect of it and just need to go through the motions.
