I didn't get very far before giving up. The game plays well and has a very authentic classic feel which is great. I think the difficulty curve could stand to be smoothed out a bit as it's currently pretty frustrating especially the bees and the owls which are very difficult to avoid (more so the owl projectiles. The bees feel very random) . I never made much progress as I kept dying in every direction I went but the game is very solid.
Keep up the good work, but please evaluate the difficult curve!
