Thanks for playing! I'm happy to hear you like the art as I struggle a lot with making it look decent haha
The movement is not the fault of your laptop or the engine, it's actually a timer in the code that I put so all enemies have time to complete their movements before the player can move again. I wanted to reduce the time or make it basically non-existent, but oh well, three hours is a not enough time for that haha
And yeah I noticed that bug way too late so I couldn't fix it on time, that breaks your death counter for the run. You can move to get out of the loop easily tho
