Thanks a lot man! ๐
Indeed upgrades screen was done on the last day so, not really the nicest screen in the world ๐ but we really wanted to get it in because upgrades and achievements were here to answer the question "Why would anyone want to play again?". Achievements show you that, you haven't discovered everything the game has to offer and upgrades make it easier for you on your next playthroughs.
About the removing block mechanism, we saw it as a reward for playing right: you can stack up a lot of blocks at the start of the game when it's easy and use them when the game takes the difficulty up a notch with the shooters and the wind zones. If a robot takes back your blocks for you, it would be like having infinite blocks, making the game way easier so, some balancing is required there. Should the robot be super hard to get? Should we make the game harder when the robot is here? Should we make special levels where we can have the robot and take the infinite blocks into account when balancing? We need to think it through but, your feelings about this have been heard. ๐
Thanks for the feedback and thanks for playing our game! ๐
