Yeah I'm definitely agree with you timer isn't stressful in my difficulty curve, I'll update that after the Jam (I hope).
The visual bug that you'd noticed was spotted by me as well, but only after deadline ends, so I just didn't get enough time for playtesting. However, there's counter embedded into each spell that work appropriate. But visualization is like "Oh, you have 5 swipe spells, i guess i just gonna take them away from you in a random frame" and then just resets spell counter.
Thank you for your review!
