Two glitches:
1. Lack of doublejump while touching walls (although it's easy to avoid, you just need to remember about it).
2. Instant death on level beginning - that one is really annoying as it increases death counter (yes, i want to finish whole game with no deaths) - i always get it around 21-23rd level, no matter what i do, but sometimes also on other levels.
