Deep Marine
Your goal is to get as deep as possible while collecting coins and eliminating enemies. You can spend the collected coins in the shop "Subby" where you can get upgrades, like speed and armor or the harpoon to defend yourself against the enemies.
Controls
- Use arrow or WASD keys to move the player
- When you‘ve got the harpoon use it by pressing the space bar (increase damage by keeping the space bar pressed). You can aim by using the arrow or WASD keys while holding down the space bar. Release the space bar to launch the harpoon

Game design-wise, I'd add more dangerous enemies and more/bigger coins the deeper you dive.

1. Vector coin doesn't fit the pixel art style
2. Upgrades are too expensive and require grinding
3. Control with mouse or touchscreen would be tons better.
Other than that, solid foundation for a game.
