Really fun little game, the boss was really fun and had a nice difficulty and fun patterns of attacks and mechanics for the blue and green waves which needed to be shielded with the right colour shield. Top tier UI for a game jam and nice music!
The waves of basic enemies could be improved with having some weaker versions of the bosses blue/green attacks or some elite enemies which have a cut-down subset of the bosses attacks to teach the player as they play before getting to the boss, also the basic enemies occasionally seemed to get stuck / stop moving. I beat the boss and got a high score of 15,950, however there wasn't an option to add my name to the leaderboard of high scores, and my score wasn't represented in the high scores list.
