Hello, we have been reading the comments and I've seen some players worried about the game becoming harder and the lack of checkpoints.
First of all, thanks a lot for playing and considering this game enough.
When we talked about making the game harder we did not meant unfair, what we should had said instead is that many enemies have blind spots on their AI's that we are yet to fix.
About checkpoints, we wanted to wait until having better stages for that, but we are seeing many players are asking for that, so we will squeeze in a small update with more bug fixes and checkpoints implemented.
Thanks you for reading, and thanks a lot for playing.
