Congrats on finishing your game :)
Just gave it a go and I enjoyed it :D so thanks for making and sharing it! It took me a few turns to beat it (I think the right sort of amount of time) mostly because it took me a few turns to get the hang of how often I could press shift (at first I was too cautious with it but it regenerates really fast). I like the running animation of the astronaut! I know you say for best results download, but for people who are too lazy to do that (like me): if you play it in fullscreen (without fullscreen the arrow keys made me scroll around the page) it seems to work fine :).
One thing I wasn't sure about was that sometimes it seemed like I could bounce off a few enemies without being eaten and other times they'd seem to get me straight away. I died a couple of times due to thinking that I'd have time to run away from one red guy if he got too near, because I'd bounce off him first, but then I died on the first chomp.
Hey, thanks for playing, and taking the time to write feedback!
The moment enemies spawn, they play the spawn animation, in which period you can push them around to make your way through. We probably needed to give some feedback on that in the game to make it obvious. :D Oh well, we're bound to get smarter in the future!
