I will be playing this game even after the jam. It is really great and I could even see big youtubers play this trying to get all endings. Only problem I faced was that the music started to loop over the same music at some point but that is small and easy to fix problem.
Someone did mention it already but I really liked the opening scene. Some robots did not take damage every time I hit them. Twist and theme were easy to feel and see.
Really cool game. After certain point it becomes really fast quickly but that is one part of the twist. I also really liked the artstyle and music was spot on.
At first I thought this was just Flappy Bird with a bit different graphics but the ending got me. Great game but some sound effects would be a nice add.
Thanks for your comment. Now when you say it I totally agree with you. It feels bit empty without some pointer for oxygen. But great to hear that you liked other features :) I will also try your game soon
