Thanks for this game! Too bad I missed your submission in 2019, but here it goes my “jugde feedback” :)
I managed to get all the knives on all levels, and wanted to take a screenshot of the level selections, but the game got stuck on Level 1 screen (probably after trying to get to the next level after the 20th).
As I saw in your other answer, yeah, I think a review on the level order might be due. I found that there was quite variety in levels types, ones requiring lots of dexterity, others requiring just figuring out the order. I had the most fun with the latter type.
The limited time on the knives and that crazy purple enemy are a great idea on keeping the player on the edge. It enforces the player to keep to a certain order and does not leave much room to think, you need to be fast and creative sometimes. I did not enjoy though when the timers were dozen of seconds longer just so you could have the time for the enemies to be in a certain configuration, that down time could be removed and then you’d remove the doubt of “Am I doing some jump/move wrong or I should just sit here and wait? Oh, the timers are long… so wait :/”.
