Cozy game, it didn't seem to have an ending but I did get all the weapons. The graphics were otherwise very nice but the character's animations were inadequate and the upgrades were just colored boxes. Some background music would have also made the mood totally different! The controls and mechanics worked well and I had no problem with them other than that you had to be careful how to build with the blocks.
I was hardlocked two times - once I fell trough spikes to the void and once I messed around with the blocks and got stuck. There should at least be a suicide button to get out of that situation.
