Hi, this is [b]Hitan[/b], one of the developers of Hapiwaku Project Team :) For IEH & IEB collaboration event that is launched after [ver. 1.4.4.0], it is planned to keep permanently, so the bonus effects are permanently available. You can freely play both the games anytime :) This time, I will let you know the development stance for IEH and IEB. Kei and I (Hitan) are mainly responsible for IEH, while Suguru and Koga are mainly responsible for IEB. All of them are the members of Hapiwaku Project Team. Each developer team keeps developing each game, so neither the games' development are stopped and slowed. IEH developer team is currently working for [b]IEH2[/b] that is much upgraded from the current IEH. IEH2 is something like the new phase of ascension tier 3. We will soon have some announcement about the detail of IEH2 :D While, IEB developer team is still beginners to develop idle games. They are trying hard to improve IEB much more. Please give us any feedback in IEB community and support to improve it together :) By the way, I will graduate from graduate school this spring. Though I previously planned to go on to a doctoral course, I decided to concentrate on IEH development. It's a personal matter but my wife is pregnant and the baby is due in this June. I'll do my best for my family and for you all to enjoy our game and feel [i]hapiwaku[/i] much more! ([i]Hapiwaku[/i] is a Japanese word that means happy and excited!) My 13-year-old daughter is also working for the new class artwork for IEH2. My wife with our baby is drawing the new world map for IEH2 too. All of us are very active to develop our game with [i]hapiwaku![/i] Anyway thank you as always for supporting us a lot! Please look forward to the future updates! :D Let's join our Discord Community and chat with us! - [url=https://discord.gg/VqbS4Wa]Discord Community[/url] - [url=https://hapiwaku.work/]Hapiwaku Website[/url]
