Yah, thanks for playing and your feedback ! We had 2 more levels done, with some other creatures and patterns, with a tiny boss fight at the end. We were running late, I added/fixed some tiny stuff instead of testing. I finished the export at ~20 minutes before the deadline, and got a big bug occurring only in the executable version (my favourite bug :s ). So there is only 2 levels and the game cycle on the 2nd one, and you are stuck when there is no upgrade any-more. My bad (one day I will not make this ******* mistake) ! Glad you enjoyed it a bit.
