Thank you so much mate! 😁
Indeed after the core concept was done, adding enemies and bonuses was our 1st concern since the player had absolutely no reason to do anything else than just drawing a straight line. The same goes with random block generation on the path, also great to get back some more blocks!
About the improvements system tho, we've mostly added it to answer the question "Why would anyone replay our game?" and it looks like it was well received! 👏
We're glad you enjoyed it! 😁
