Thank you for your useful advice, wowoshou🤝 wowoshuangshou🤝🤝! This game is in its early development phase, afterwards I'll add save&load system, changing clothes system and trait system(this is what did you say boosts), and at least one new mode will be made, in which Linda could manoeuvre herself to entice enemies to knock obstacles. The collision judgment is a little loose indeed because I want to lower the difficulty. Maybe you mean these floating obstacles? OK! I'll add a shadow to each of them so players know what's their true road.
At last, my game is deindexed by itch.io. WTF
