The idea is so cool. I think you have to remake the jumping to make the platformer better. Also, I didn't quite get the Tetris, maybe you can add a tutorial? I loved the concept!

the bloc character is too heavy during the platformer , his jump is not handy at all ^^"
despite all it's a nice game idea  :)

Only thing i can say is refine the controls on the platformer, otherwise its a great concept and really enjoyable game 10/10 ;D

Heya I am doing video feedback/first impressions/just my honest thoughts. Really awesome entry!

This is actually pretty fun concept. I ended up playing tetris most of the time lol. It needs more polish especially with the jump and platformer aspect. But playing tetris (fun!) and getting the pieces to continue navigation is a great idea. Although the platformer aspect needs some more work. The controls was confusing to me... I have to press 2 directional buttons to rotate? But overall i think it's a great concept, i kept playing until i jump into an infinite falling pit lol. I think the leap of faith needs a hint for player to jump down there. It's pretty good work and idea for a jam game. Great job guys!
