Thank you so much! I really appreciate it, and I'm glad you had so much fun playing it.
The single hit taking off multiple lives has been updated for V2 and will no longer be an issue when that gets pushed out.
As for the level design, you're absolutely right. I didn't give enough time to fully plan out the levels like I would have liked. I've been going through with much more intention when planning the levels. I've gone with a duel approach. Keeping the preplanned levels (with better design) but having a procedurally generated free play mode. That seems like it would be the best of both worlds.
Thanks again for your input, it is very helpful. I'll make sure to let you know when I get V2 out.
