Glad you enjoyed it! I didn't think about VR but that could be super fun to make!
Yep a few people have mentioned camera adjusting will definitely be adding that in a cleaned up later build. As for powerups, the game is balanced around no upgrades right now but a great plan for "Moon Blob 2" ;) haha - Perhaps with levels, waves, upgrades, skill trees etc. I'm thinking something like what Gemcraft did with their games.
Thanks for playing!
