Hello, solid game you've made here. I played it as part of an event going on in the howlongtobeat.com forums where your game got voted for, and it was a lot of fun
The heat systems a bit broken. I think that it's meant to add some strategy to the game but
1. It was a bit easy to break, i had over enough heat by the end of the 3rd floor to explore every single folder and chest on all the subsequent floors if i found one or two ice creams, and my run ended with 153 heat.
2. It also (atleast for me) caused me to be less strategic and just start rushing.
All that aside, this was engaging and fun, and that's what matters. With a bit more polish and a bit more meat on its bones, this could be really good. I've already wishlisted the game on steam and I'm looking forward to the full release.
