Nice creative concept. I like how we have different gameplays in each scene with catchy retro music - felt nostalgic like in famicom games.
However I think this is overscoped. Leading to the reason why it felt unbalanced or unfair to play. Like we can only survive 1 hit. The map design in 2nd area seems dead end maybe because the hit box is unclear. The boss attacks are overwhelming it takes up almost the whole space without warning zones.
Also what is point of exporting Android version if there is no controls to support touchscreen? 🤷♂️ I hope you consider browser version next time.
