Thank you for playing and putting your time into writing some feedback! It's awesome to hear what you think works. and what doesn't--and I hope I'm able to revise and make a much better game out of it.
And yeah, it's my fault the game gets laggy at the beginning; the funny thing is, the reason why it does is due to the way that I make zombugs disappear when out of sight, so I'll definitely work on fixing that. For the computers, I'll definitely rework that too.
So thank you for playing, and I'll (hopefully) come back with something better! ;)
