What an amazing platformer! It's really well made and well polished for the time limit, I'm amazed it was made in a single month.
The graphics are lovely, and the music is cute even if it gets a little repetitive. The whole cupid arrow mechanic is cute, I loved seeing the different combinations you could make! I specially love that there's a gallery to fully appreciate the lovely sprite work. The 10 coin collectibles were nice, some were quite challening to find but not unfair, and the reward of the extra lewd ending screen was lovely, not to mention the whole secret ending screen deal is quite similar to what some older games did with their secrets, I like it.
Only criticism I have is that I would've preferred to jump with spacebar and attack with some other button, but that's a very minor issue. I also found a fun little exploit where continually pressing S in midair made you fall slower, which was useful to make some of the wider jumps, it felt like a cool little strat so I actually found it fun.
In general it's a great entry, one of my favorites so far. I would love to see more! Amazing work ^^
