I have to say for an rpgmaker game this isn't half bad. I haven't finished yet but i just killed the stupid bulletsponge miniboss. You then get two choices to clearly "die" or obviously continue on with what the game wants and go through the portal. I liked the joke happy ending, it was good. What i don't like is they didn't think to include an option to go back to before you made that choice, instead of making you kill the boss that has way too much health.
tldr - good game so far, just had to vent
edit: darn guess it makes sense that was the end, good game though, the writing was really well done and I hope the creator makes good progress in the future.
