Hey, thank you for the in-depth feedback! We're putting a new browser version out very soon with a pause menu, scoring, and proper game over, and the final version will have those fully polished up.
As for the bullets and cleaning up the corrupted blocks, that was a very common piece of feedback I heard during the jam and I totally agree with it. The full version will have multiple guns with different purposes, including one that lets you trade bullets for much more screen-clearing potential. The different guns also have a way to tie back into the 2D mode, which I'm very excited about.
And for everything else, rest assured we're working to make the full version a game people can enjoy coming back to again and again! More weapons, more enemies, more bosses, more Flapper. Thanks again for the suggestions (I'll play around with that minigun idea), I really appreciate you being invested enough to want Blocks for Babies to be the best it can be!
