Great game, Thumper vibes :D
I have a few suggestions that I think would enhance the final game :)
- The time after dying could be reduced from 5 to 1, or even remove altogether. Rhythm games benefit from being in the 'momentum.' Having to wait 5 seconds to play again kills that momentum.
- The green color of the bomb is a bit confusing. Typically in games, green is a color associated with "good" collectibles. Perhaps making it red would be ideal, but then the player might confuse it with the crab!? Maybe aother option would be to replace the crab with another animal?
- When you're attacking, you can't switch lanes. If you continue to work on this game and add modes where the level moves faster, or where more things are happening on the lines at the same time, it would be good for the player to be able to cancel the attack to switch lanes.
Those would be my suggestions, I'm giving them because I really think this game has potential :) Also I'm passionate about rhythm games of this style.
