Thanks for the comment! Glad to hear you liked the concept but sad that you experienced issues.
Could you elaborate on the problem with the platforms? Were you not able to jump on some platforms at all or was it just difficult? Did you notice that you can jump a bit higher by pressing the jumping button longer?
Do you remember what level you had the respawning bug with. Was it perhaps the same level than CottenEyedJoe95 mentioned in their comment?
About the lack of tutorial, I thought that the concepts in the game would be simple enough that the player could learn them by experiencing them and would not need a separate tutorial. Like in the first level (which was meant as a kind of a tutorial) the player would see ghost after dying the first time and then notice that the ghosts can also press the buttons and help the player to get trough the trap. Or that was at least my thought process. Did you feel that the game mechanics were not clear enough without written instructions?
