I played through this on my phone due to being on vacation (and it took me awhile to beat for that reason as well), but I legitimately had a fantastic time throughout. Only 1 death, and I won the game with 7 air tanks left over!
There were a couple mobile specific issues, where story and upgrade descriptions would be cut off, which made some mechanics slightly confusing. I also felt like my second run was too easy, where oxygen was no longer any issue at all - and the oxygen room was so expensive I ended up never using it. Nonetheless, fantastic game and the devs did an incredible job!
