That's amazing to hear!
Though i wonder how that'll work with shapes added into the mix.. then again, thinking about it, having to switch from puzzler to bullet hell due to an enemy attack sounds like it could be very fun. It would be much more chill than normal battles, as you can take your time to shoot everything down, so maybe it'll require cranking up the number of shapes to remain equally threatening? Then again, you can always adjust the difficulty slider for that...
Well, i'm looking forward to whenever you get around to releasing this ;)
