This is a cool Mini-Metroidvania! I like the Visuals & Story setup. The music is great too, but SFX were missing in some places. I ran into some minor issues which didn't really break the game. Here is a short list:
- Hard to spot enemies
- Taking damage needs better feedback
- Dash is a bit broken
- Banshee scream ability could use a tutorial before the boss
- Current selected ability should be displayed in the HUD
Overall, this game really captures the Gameboy & Jam themes well. Good job!
