Thank you for playing our game!
This was our first jam and we started a bit late which led to our scope management being a bit off considering our experience working under time pressure. We definitely didn't manage to ship the game that was eventually released which is unfortunate, but we still learnt a lot from it.
Your feedback is really interesting, a bunch of the ideas you mention we'd not even considered. A size indicator could have definitely been useful, it's easy to take things for granted as someone whos worked on it a lot and little details like that easily slip through, especially under time pressure.
We were hoping to do some of the things you mentioned we had art ready for another enemy that didn't make the crunch which was really unfortunate as it could have brought a lot to the gameplay. A cleaner look to the background and a UI was also something we wanted.
But I'm glad you enjoyed playing around the shrinker and managing to find elements of strategy, it was something we too found when playtesting, which just led to us adding things to the list of "post-jam content" :'(
