A solid first level demonstrating the game idea. It's a cool idea and the sound track you created is nice.  I think, unlike the comments below, that the timer is good idea and makes it a bit more challenging than if the player could control the changes. A pity you didn't have more time to make more levels. Good work!

I actually really liked this concept! Wish there were more levels! I think it would be nice if we could visually see timer or be allowed to switch between player and builder ourselves. That might help with having to wait for the timer to exhaust before switching roles. Regardless, I think this has potential for some great mechanics!

This is great and fun to play game!

I played the game to completion, and it was very fun! I also personally liked how the character controls (it feels Super Meat Boy-esque). There were a few times I was frustrated because I tried to place a block and couldn't, but this might be because I'm playing on an ultrawide monitor and it was near the edge of the screen. I think the concept of this game is really cool, and I'd like to see more levels in the future. I also think you should add a button to switch roles before the timer runs out because sometimes I was just standing around waiting for the timer to expire. Oh and the song that plays during the game is a banger! Thanks for sharing this game!
