This was an interesting game. After reading the instructions, I still felt the need to click the buttons in the main menu (which did nothing) until I remembered that "Z" selected options and "W"/"S" changed menu option. The controls were a bit hard to work with at first and I wasn't prepared to need my mouse for clicking the action button, leaving me wondering "How do I get higher up in the game?" The difficulty seemed to ramp up immediately too.
Overall it was cool to see how you used the asset pack to create interesting environments. I particularly liked the bee level with the inverted trees. That was an interesting design decision that I liked.
Unfortunately the candles seemed like they could have been anything, though, like this game could have been using a different item as part of a previous game jam submission and you swapped it out for candles. I also didn't see anything related to the "breath" theme.
I like what you're doing, though. It was fun. Keep it up!
This game was fun to play and I liked the high score element. The only reason I rated it a 3-star was because it lacked the "breath" theme, there was a lack of sound elements, and there were minor interface issues with the floating point numbers.
Overall it was a good game and I hope you keep making games.
