Seriously so good. I struggled a little bit with the placement mechanics (I think I was expecting the bomb to snap to the middle of the tile rather than have free placement), but after I locked in I just kept going. Dropping a red bomb and then having to hightail it out of there right before getting blown to bits and pieces had me going every time. So much fun!
A little more feedback (like a little audio buzz or shake) when trying to place a bomb incorrectly would probably help. I think I was mistaking an inaccurate placement of my bomb for the game eating my input or something glitchy happening. A little feedback would help let me know I did something wrong!
Top tier!
