Hey man, this is a really fun game. Great work! It's snappy and the gameplay feels smooth and engaging.
But I don't know if others had the same problem I'm having with it though. Every time, around the 4th or 5th wave, the game just east up all the memory and crashes. It was using 8 Gigs of RAM the first time I checked after it crashed. Then I tried the 32 bit and web versions, but the same with all of them. The web version even gave me an Out of Memory error.
If you're still updating the game, then I'm looking forward to messing around with it for an hour or two more when It's released.
