This is one of those entries which I could totally see me playing on actual hardware as a kid. The art direction is lovely, the game has upgrades and repeatability with a cool score chaser loop!
Graphically the game looks spotless, I love everything you presented and the boss icons slowly gaining color as you defeat them is a lovely touch!
Bitcrushed sound effects made by the dev, a banger soundtrack, only bad thing is the sound balance of the waves, they drown out many effect you would probably want to be over them.
The game is lovely, super cool job!
