That time mechanic was really cool! It combined with the explosive made the game really fun!
Especially the starting levels, the way new mechanics were getting introduced every level
First the explosion
Then the timing mechanic
And to top it all up, the boost you get from another bomb
But I feel like it could have grown more, I was expecting stuff like setting up 2 bombs to perform a combo, like more complicated stuff which required the player to actually think as to how and where to place a bomb. (It reminded me of portal lmao)
After beating the game, I was left wanting more, which is a good thing, as you can expand the game much further lateron. I can see this idea resulting many fun puzzles!
You did a great job! :D
