Very interesting! The mechanics are intriguing, the monster designs are cute, and the soundtrack is cool. The movement is a bit janky, but manageable. Developing this many distinct, complex mechanics in such a short time is truly impressive!
I was a bit surprised by the testing of luck mechanic. It was phrased as if it were a threat for using too much luck, but it usually just refilled my luck completely, something I had assumed I would be doing mostly with cards.
The audio is mixed a little loud; combinations of sound effects regularly peak the audio above 0.0 dB.
Unfortunately, loading back in before the exit after losing to the final boss caused the door to become locked for me again, with me being unable to get keys.
All-in-all, great work!
