Ohh, are the worlds procedurally generated? I've been wanting to create a similar game where you travel to different worlds (inspired from the game "Wizard with a Gun")
It was hard to dodge speedy monsters. Maybe an indicator of incoming enemy would help? I also like how you bleed as you scramble to get to exit and ask Tenissa for help.
More assets on the worlds would really improve the aesthetics of the game (bushes, trees, rocks), but you've done a great job for a game developed in a week. Well done!
