An interesting, beautiful game! =)
My results:
I did not overcome the last level, I was already a little tired of the game.
What I noticed:
- when you restart the game (close and start again), the failure counter is reset;
- "locks" sometimes do not appear immediately, but with a delay;
- at the start of the level, the player's ship looks in a certain direction, when it loses and respawns at the start, the ship always looks to the right (direction = 0);
- sometimes it seems that the ship has not yet touched an obstacle, but has already lost, I suppose the collision mask is a little more than sprites;
- different types of obstacles are not synchronized (it is easier to see it at level 40), that is, over time they move differently than at the start of the level (room) and a situation may arise that 2 obstacles create an impassable place (but for a short time, of course ).
These comments are not critical and do not affect the fact that the game is good, but perhaps they will help in the development of the game, if planned. =)
