hi! thanks for your feedback, we will check the crashing part.
for the platforming, the 10 seconds cooldown + short dragon appearence isn't a bug : one tip that might help is that double jump is possible, and that the dragon will be summoned below the character when it's jumping ! this should allow you to reach higher platforms o/
i will add those details on the game page so that it's more clear for future players ! thx again for the review !
