Can I play Seiklus in windowed mode?

I recently downloaded Seiklus at the recommendation of a GamingSE blog.

I had it on my old laptop, and was enjoying the game; I would like to enjoy it on my new laptop as well. The problem is, I can't remember how I got it to play in windowed mode on the old laptop. So, my question is:

How do I set Seiklus to windowed mode?

Solution 1:

No, but there may be a workaround. From the comments on this archived thread made during Seiklus' development, changing windowed/fullscreen was not an option and the author never added it as per the changelog. The possible workaround is that the author added in different resolutions which according to this is toggled by Ctrl + R. I hope this helps.

Solution 2:

Try hitting alt + enter while you're in the game.

Solution 3:

If the other answer doesn't work, I know Seiklus was made using Game Maker, and that the default key to toggle between windowed and fullscreen mode is F4.
