The levels are so long... The run was pretty good, I died only once on early levels and a couple times near the end of level 5, as expected. Also the game softlocked a few times where I had to restart from the last checkpoint since enemies would stop spawning. Also way too much lag in some parts, but this is a demo, so they'll probably fix it when the full game is out. It can probably be a lot better, but this is pretty good for me since I'm not used to playing these kind of games.
