the game got fixed, here's my thoughts:
the placing blocks mechanic feels a little janky, the player often gets kinda stuck between the blocks, its fun nonetheless.
i was kinda lost on where to go, but it was still fun
you nailed the pixel art look, really looks like one of the older games for an atari or something
the player felt really weird to control, the hitbox seems to also include the little jetpack behind him which makes it hold on ledges
i'd say this game is a solid 6/10, good job
