Because I love your concept, it is my duty to provide you valuable feedback:
First of all, the game seems very incomplete yet. I was able to complete Flannery and Mt. Lady's requests by doing absolutely nothing, and then I didn't get the promised cutscene rewards.
Secondly, the game isn't clear as to how many of each object (crystals, batteries, etc.) you need to find. I picked up one battery and I was left wondering why Viola wouldn't react to me having it.
Thirdly, we need some swimming/floating controls for the swimming pool. I fall inside while tiny and I'm unable to climb back up.
Fourthly, Nurse Joy's shop has NOTHING to sell! I was expecting to buy the drinks there...
Fifthly, several of the girls (Elesa, Malva, Rika) don't even talk! The female Team Skull Grunt is not even animated yet! She's like a statue! XD
Sixthly, a minor one but most of the girls don't have a collision box on their feet.
Just a suggestion here, but for the ones that are barefoot or wearing flip-flops or sandals (basically all that have their feet exposed in some way), it would be nice to walk up to their feet and press E to tickle them. I would cause the tickled foot to twitch slightly and the girl to play a giggle sound effect (and it could be an alternate trigger for having Bea crush you).
Keep working on this! You're doing great.
